Step by Step - How to flash your factory radio when adding a new amp to your Harley Davidson 

Thanks for your video. I purchased the tool, downloaded the software and finally flashed my own radio. Your step by step is spot on . Great job. I did it on a 2023 RoadGlide Special.

I just bought the flash tool as a rental. The setup is similar as far as the downloads go but a bit different from this year old video. I downloaded it to my pc along with all updates necessary. I’ll install tonight on the bike wish me luck. Thanks VA

For some reason I had to delete it in download the whole thing to times but I finally got it the second time. Thank you

Lot of great information.

Great video, helpful

Brilliant and great information!!!

I purchased the Hertz stage 4. Just completed the flash on my 2016 Street Glide. Only issue was how my connection was a little stiff coming out of the fuse box cover. Great video I will comment on all the install videos as I install my system. Only one I am nervous about is cutting my saddle bag lids.

Just flashed 2023 FLTRXS with your loaner tool. If you count the time I stared at the unit before realizing it was really that simple I spent 15 minutes. 13 of that was staring.

I NEED this.. I assume my 2018 road glide special wasn't flashed, cause it doesn't sound that good. Granted it only has rockfords in the fairing, and a soundigital amp. Unless of course it was flashed already, and just sounds bad.

I have a tri glide also I would like to see the rest of this build and how it goes I want to put speakers in places where speakers should be and also some sort of enclosure in the back or some type of application where bass can be inserted because the tri glide has a trunk

Nicely informative video, I didn't quite get the answers I was looking for. I have a KAC-M3004 4 channel amp, and it will turn on with line input or remote 12v. Would a flash be recommended for this amp on stock harley gts. Thanks

I just ordered a stage 4 hertz with the sp4.900 and soundskins fairing kit for my 2019 streetglide on 6/8/23 I have not started the install...waiting for my off days with much anxiety lol...My question is I mostly use android auto,so should I still do the apple carplay play flash just in case and will it affect android auto in anyway? I use a ottocast for wireless android auto. Also appreciate your videos and the work you put into your kits.

Great video very informative. Ive been down this audio rabbit hole all day. You say in the video part of the reason you’ve choose the default setting is because it turns on the rear speakers. So if i don’t want the lower speakers which i assume is in the leg faring. Can i use the 6 Speakers - Upper Fairing / Saddle Bags / Rear Pods / 2 AMPS and get the same eq curve or if i was to do the rockford flash will that enable all my speakers and have the flat curve you speak of? With these being factory flashes will my local dealer be able to do this? TIA

What about 98-13 factory radios? Is there a way/need to flash those when adding an amp?

I have two GZ front speakers and the Sounddigital 800.4 amp. which flash should I use for this? In default the 1 Amp 2 Speaker, the Rockford Fosgate or the Soundz? It's important to me that not too much bass is lost.

Great info Jay! Would you use that same flash (6 speaker/2 amp) if you were just doing the 2 fairing speakers and an amp? It gets a bit confusing but I think that's what you recommended.

Wow. Super easy with those instructions. Still need to call yall to figure out if we can get more out of my SD 400.4Evox with this flash.

I have a 2016 Ultra limited. The Stereo crashed while under warrenty and was replaced. Im going on a ride with my wife and friends. The Headset doenst work and the CB wont come on unless someone else keys in on a different CB. Apparently there is a option that needs to be set to internal. Will your programmer work to fix this issue???

Hi, What about 2019 CVO SG? It has a WHIM, 6 Speakers and boom audio stage II, but on the software it says “Do not flash boom audio stage II…” in bold red

Thanks so much for this video Volunteer Audio! I was so exasperated with Harley regarding Carplay support because if I buy a $45k bike it better has at least 2 bells and 1 whistle on it!. I bought the tool last week, and installed everything just like you guys showed here and it simply works. No more cussing at the crappy Harley Navigation!🛵

I have a 2016 Street Glide and purchased a 2021 GTS Boom head unit to install in place of my older unit . Will this tool “Marry” the Boom GTS to my bike when I install it ? Thanks

I bought the Rockford fosgate stage 3 kit. should i be programing the radio with the 6 speaker 2 amp flash or the rockford fosgate flash?

Do you recommend flashing the radio before the amp/speaker install or after? Does it matter? Also, do I have to do the Apple Car Play flash is I have an Android phone? Is there any benefit to doing so? TIA

I have a 21 SGS I bought new and the 1st thing I did was put in different speakers and a little amp, I went with Hogtunes REV225 Amp and 462F because it was plug and play no flash required, sorry I didnt even know of you guys at the time! It's way better than the stock garbage anyway. Would purchase this and doing this flash improve it even more? Thank you.

SO, I purchased the Hertz Neo's from you guys(690's, SV/SX165's-front and rear Powered byCicada BDA10000.4) can you tell me what the difference would be between the 8/2 and the 6/2 flash. or should I experiment between the flashes? also have a DSR1 in line.(thinking of removing)

Do you flash the radio before you install the amp and speakers or after the install? I’m planning on buying the 4 stage kit for my stock radio. 2018 RGS….

Great video Jay! If i wanted to keep my Boom II amp and fairing speakers (for now), can I have the dealership flash my radio to fix the eq curve? Possibly to the 6 speaker, 2 amp factory Boom Audio flash that you mentioned in a different video? Or does the dealer have to flash it to what the bike actually has?

While trying to flash with the one you recommended , no sound from the speakers. I have the wild boar audio amps and speakers. So I used the wild boar option and they work …🤷🏻‍♂️

If you flash radio for CarPlay and don’t have a whim then decide later to add the whim will it work with the original radio flash you get with your tool or do you have to reflash a second time?

Hi fantastic video, does it flash a sound stream amp with kicker 3 way speakers?

Is thisn eeded for a 2023 street glide flhxs. Looks lke it has the soundstream radio already but wanting to do a 4 channel,replace front speakers and add rear saddle.speakers

Great info here Jay! Wondering... is the "6-speaker, 2amp" flash any different from the Rockford flash? I'm wondering specifically about the low-EQ gain differences that may boost the low range when using a single amp with 2 speakers. Thanks!

Will this work for my 2018 CVO road glide and will I be able to change my speakers and amp out afterwards?

I work for a shop and we have the Techno Research hardware already. My employer asked me to familiarize myself with how to use it and what we can do with it. The how to use it was perfectly covered in this video. Thank you. My only remaining question at this point pertains to bikes with the boom systems or other factory amp add ons. This device is ONLY for the radio itself correct? On those bikes my thought would be (if the customer isn't happy with the "premium sound") 1... flash the radio, 2... remove the "factory" amp, 3... replace with aftermarket amps and speakers. This seems to be the best way in my opinion to deal with the cross over points in the amps and get a full range signal to work with. Am I on the right track in your opinion or am I over thinking things?

I have a 2015 and would like to flash my radio. Will the 15 stock radio flash to use the Apple Car Play?

If we have the jumper already installed for CarPlay, does it need to be removed after enabling CarPlay and flash? Bike is 2020 street glide

good morning Jay. i am not sure i am understanding this. a few days ago in your "why you need to flash" video, i had asked about a flash to get rid of my biketronics BT-35. you had indicated that i needed the boom 2 amp setting, but now you indicate that they can't do that without the boom amp? about the 6:05 mark. you indicate that the dealer cannot do this without the amp installed. so is there a setting they can do? i may have just misunderstood the information

Looks like you only internet connection to down load the App.. But will you need internet connection when connected to the bike to make the changes..that can make a big difference as many don't have internet where the bikes are garaged? Seems well detailed otherwise

Great video and very detailed. Does the program work with Apple MacBook as well?

Does this work with other installs or only with kits you sell? I currently have yellow basket Gz on the way and currently use Alpine R2-s65 speakers connected to kenwood xr401-4 and LC7i converter. What benefits would this flash do and what setting should I choose?

Hi will this work if you have the cvo with the Rockford system?it’s a 22Cvoroadglide

So still use the 6 speaker setting when I'm only using an aftermarket amp and 2 speakers on a street glide? Correct?

I have a 2019 Ultra Limited with J&M Rokker 800W 4 speaker system. If bike is off, system seems extremely load and clear. At 70-80 MPH music can barely be heard at max volume. Will a flash fix this issue?

Is this the same process to use to add rear speakers no amp and stock radio on a 21 Streetglide??

hi jay i have a 2017 street glide cvo i swapped the radio for the boom box gts my technoresearch computer can't configure the amps. Specifically, 4 Stage II speakers (Fairing Upper & Saddlebags) with 2 amplifiers.

After you flash the radio, will the speaker outputs be at a low enough level that you can use it for RCA inputs instead of the high inputs on the amp?

I just flashed per instructions 5:00 my 21 RG with rockford 6 speakers and amp.CarPlay appeared but sound disappeared , reflashed multiple time with same results.

I am going to buy this tool. Is the boom flash still the best one even if I am using a Diamond Audio amp?

i was just wondering why the 6 speaker flash instead of the soundz which has a flat curve, just curious

Quick question I have a 2023 Ultra Limited and have the WHIM installed, will this flash the need for me to connect a wireless headset so that I can get WAZE and Spotify to work without wireless headset

If you flash for Apple car play, do you need the dongle thing as well?

I need you to do my 2022 trigide with Amp speakers and your Samsung play

Even if you're only doing a stage four, the six speaker flash is the one to choose?

Is there a way to find out what flash a bike has on it or if it’s flashed at all thanks

So you flash the radio before you remove your old amp or do you install the new amp and speakers then flash?

i may have been misinformed. do you need to program anything if you're JUST upgrading speakers?

Jay I have a 2009 harley ultra classic, with everything stock radio system, Do you recommend a certain package upgrade for my bike?Mark here

so when you flash your radio does the software version change?

Could a Harley dealer do this same flash? Or do I need your tool?

Do I need to reflash if I decide on different speakers later?

If you update your Harley radio using Harley update files. Do you need to reflash your radio again after updating?

Do u have this for can am spyder F3L

So my question is, actually, 2 parts 1. Do you have to reflash if you flash for 1 amp and 2 speakers and later decide to add 2 more speakers? 2. What is the cost to rent the module?

Do you lose your fade front to back with this flash? I have no fade after the flash????

I was having an issue with Apple Play not working after I flashed my radio. I called Tachno Research and the technician tried to get it to work but couldn’t. He said the software might need updating. Have you ever had this issue?

Will this flash work for android auto as well?

I installed a wild boar kit and listened to it already so now how do I flash it?

I cannot clear the following codes after using your recommended flash: U0186c - Lost comm w/AMP 2 AMP COMMUNICATION DIAGNOSTICS U0186c - Lost comm w/AMP 1 AMP COMMUNICATION DIAGNOSTICS I clear them, then it keeps coming back! I flashed the radio using your rental tool and the recommended flash. Installed the Hertz amp 4.900 ( With plug-n-play harness ) I purchased from you for GTS head unit. How do I clear these codes that keeps coming back? Amp is on, everything sounds great! Just cannot clear these codes

How much is a license if you already purchased the tool

Can you show the process on how to start the Apple car play after this process??

Can you flash a 2013 Street glide radio?

will this work with a thundermax ECM?

Can i btpaas my fob with this tool

i did this on my 2020 RG Special, i installed the Precision Power powered sub. when i flashed it my front speakers wont work

HI, I just bought a used 2014, its got a stage 2 upgrade, boom audio, 8 speakers. I've got 1 channel out on the amp on the front and on the back. (i took to the dealer for them to finally tell me its the amps). I noticed in the very big red letters there, DO NOT FLASH BOOM. I've got the 8 speaker boom. Would this work? (let alone the 6 speaker setting vs the 8 speaker setting)? any help would be great before i purchase new amps. The bike has 1 blown speaker. And I do notice the low mids are super punchy, I turned mu bass down. I'm optimistic the flash flattening out the bass will help if it can work on my 8 speaker boom.

Do you flash before the install or after?

Hello Can I just ship it to y’all?

Great video. However, this program does not work if your computer does not have windows software.

how much to purchase outright?

So it tells me the USB is not found in a plug-in a different one and I've tried both ports keep saying the same stupid thing. I should have known this thing wasn't going to work

Mine says I’m missing drivers

yeah, dont show the radio working, just show your advertisement

I need this tool for a 2023 Road Glide Fltrx. Where do I purchase?
