How to Change Car Launcher Theme and APP  

I am debating between this and an Apple CarPlay module. Once this is installed, is there an firmware update that will allow settings within the original OEM head unit to be customized? As an example, the OEM head unit has a setting where the door locks can either all open when you use the key fob or the driver door only with the key fob or the smart key on the door handle. Changing the level of the back door hatch in the cargo area can be done through the OEM head unit daytime running headlights can be turned on or off within the OEM head unit. These are just some of the major ones that I would not want to lose access to, I did run a test where I took the negative battery terminal off of the battery to see if the settings stayed how they were programmed or if they would reset and they did stay the same as they were originally programmed in the head unit. I’m wondering if you guys cannot provide access to these essential vehicle customization OEM options if we just have to set up the vehicle the way that we want prior to putting your aftermarket head unit in and hope that the settings never revert back to a factory reset, as I don’t know where that information would be stored if it’s not stored Within the OEM head unit? As an example if I have all of the door locks set to open at the same time through the OEM head unit and I put your head unit in will that setting remain or will it revert back to the factory setting of just the driver door openingwith one push of the unlock on the key fob? If all of the functions that we set up in the original head, unit will remains stored on the main computer of the vehicle. I may be OK with that, but if they could ever be wiped out while your head unit is in and the only way I would have access to change it back is to reinstall the original head unit that is just unacceptable to me as I’m locked out of way too many features on this vehicle, I think you guys need to address this publicly as everyone needs to know what they are getting themselves into and quite frankly you should create a firmware update or an app to address this issue if you don’t have an answer. Please let me know as I would like to purchase your unit, butit’s not acceptable to lose all of those features. Time is of the essence thank you for your response.

Does It work in yt5760b?
