Let's install your BMW Z4 E89 Android 10.25-inch multimedia together. 

Thanks

Optical fiber is mainly used to transmit OEM information, it is not to transmit audio. So you definitely have to move the fiber optic wires to the android harness; If you must connect AUX IN to get Android audio, you must do so. This is the only workaround. The knob may need your help adjusting it for me.

Now let me answer your question: 1. You can install and use Google or WAZE navigation in PEMP Android, and navigation requires GPS antenna to search for navigation satellites; 2. When you insert the SIM card, PEMP can connect to the network through the 4G antenna; 3. If the above 2 functions are not used, you can not install them; 4. It is recommended that you install it where the signal can be received. As long as there is no hardware coverage, it can search for signals.

Your question is very good. Yes, after installing the PEMP Android screen. It is fixed. It cannot be close the screen again.

This is a good question, pls send me your bootlogo, 1920*720 JPG, then i will make the software to you, you can update the PEMP android screen. My email: service@pempcar.com

if your phone is a Android, you need install below link apk . drive.google.com/file/d/1Wp5XHATlJ9DNWXZE967lB4w53LqSheuM/view?usp=drive_link

@@pempcar Is Iphone! I heard about zlink but on the market is not longer available!

You can buy this product from Amazon. You can get it as soon as next Monday. The link is as follows: www.amazon.com/dp/B091CM9BT3?ref=myi_title_dp

Which year are you Z4, can you send the picture of the driving cabin to my email service@pempcar.com, let me confirm.

Yes, it fit your 2010 Z4, what you need to pay attention to is, 1. If you need the Android control knob, you have to purchase it additionally, the link is as follows: www.amazon.com/dp/B09BVXZ94G?ref=myi_title_dp 2. Because your original car does not have a screen, you need to set the original car's display as the original car without screen. Setting method: Settings > Factory Settings 070305> vehicle > car without OEM monitor, Choose it.

All functions of the original car are retained, and the operation is the same as before, except that when you want to use Android functions, such as Google Maps, CARPLAY, etc., you can switch to Android mode.

@@pempcar thank 🌹

Yes, You are right, because it becomes a 10.25-inch HD display and can't be Closed down anymore. It's always there vertically.
