3G unreliable, change music player/wallpaper radio/ install apps

[Charly]

Hi,
I recently bought a Pumpkin radio and I would have some minor issues where I could need help. My unit is:
Android: 5.1.1
MCU: MTCD_LMV2.30_1
Processor: Quad (Intel 1.2GHz)
Kernel: 3.14.0
Model: A-Media AUTO
 
So here are the issues:
1) The 3G connection is somehow unreliable. Sometimes when I start the radio the connection does not work. When I then switch on and off the flight mode then it works again. Is there any fix to make it more reliable?
 
2) I would like to change the music player to amazon music. So target would be when I jump between the different modes with the "mode" button (on the steering wheel) amazon music would start (open). in addition it would be nice if I could skip the video player as I do not intend to use it.
 
3) As all my interiourlighting in the car is green, it would be nice if the theme of the radio app would be available in a green color as well.
 
4) the build in app "easy connect" does not work with my iphone 7. I can not connect.
 
5) I can access play store and install apps. I can directly start the apps then. But either after a while, or immeciatly the app icon disappear and can no more be found. The app is stoll there on the drive and when I go to play store I can restart without downloading it once more.
 
Would be great if you could help in these issues.
Thanks a lot.

Hi,
For the 3G conenection problem, first please try to change anther USB slot ,because it might caused by the unnormal power from the USB. If this don't help, then try to change anther 3g simcard .
For the music problem and easy connect app problem,it might be the compatibility problem.Could you provide your order number or buyer ID so that we can know the model number of your unit and give you the suit solution.
For the theme problem,sorry,we can do any help for you.
