Hi there,
thank you very much for the Info with RDS and the rear Cam. I will try it today.

2. Can you tell us more about the automatic adjustment of brightness?
I used Tasker to control automatically the Display Brightness in relation with the current Sunset/Sunrise of the present location.
For those who dont know what Tasker is, it is an android automation/script Program to automate tasks and macros. It is similar to Eventghost in Windows.
The macro works like this:
Get actual Location(GPS or hardcoded)
v
v
Calculate Sunset/Sunrise times of the location (the calculation is on Board with javascript so no need for Data Connection to wheather websites to parse the times online)
v
v
Compare these times with actual Android System Time.(<<-this is why i needed a stable system time)
v
v
Set Display Brightness to dimmed at night or lighten at day times(the brightness values could be adpated in the macro).
The loop is set to 2mins(could be adapted). For instant I am using hardcoded coordinates but it could be simply modified for GPS use (in fact the code is already in the macro but deactivated)
What you need is the Tasker apk (I am using ver 1.3.3u2, it is lightweight and works stable on cusp)
Here is the complete Export of the Profiles and Tasks for the Display control:
http://www.file-upload.net/download-8316338/Display_ctrl.zip.htmlI already hardcoded the coordinates of Moscow(55.75 N 37.61 E) in this macro.
-Unzip the content into the Tasker Folder that you will find after Tasker Installation on /sdcard/Tasker.
-Open Tasker Menu and click on "Data" then Restore.
-You will get 3 Profiles and 4 Tasks.
-Just push the ON/OFF Button on the right side so that Tasker get active and works in background.
Some Remarks:
-You can change the coordinates for your location: Get your coordinates here:
http://gpso.de/maps/ in dd.dd Format(yellow rectangle) and put them in the "Sunrise Display Control" Task at line 6, 7 and 14, 15.
-You can change the Display Brightness of the Day/Night mode at lines 9, 10 and 21, 22 of the "Sunrise Display Control" Task.
-IGO:
In the "IGO UND DISP CTRL" Profile check the path of your IGO APK.
I use IGO for Navigation, unfortunately the grafics engine of IGO turns black for a sec when the tasker adjusts the Display Brightness. To avoid this, there is a 3rd Profile "IGO und DISP CTRL" that turns off the Display Control Profile when IGO is on. This avoids the flickering. The Display control reactivates as soon as IGO is closed.
I don't know if Navitel(seems to be popular in Russia as I've read the thread) has the same Problem as IGO? Pls Check this and put the path of your Navitel apk instead of IGO. If there is no problem you can simply deactivate or delete the "IGO und DISP CTRL" Profile.
I hope this will work fine for you.
I am working now for an automatic volume adjustment depending on the speed of the car based on GPS-Speed. Unfortunatly the cusp Radio has no connection for the speed signal wire that comes from the car.
My initial macro already works fine, the problem is that I can't control the general volume of the Cusp Volume Control App cause it seems to be a proprietary driver. The only volume that I can control at the moment is the Android Media Stream Volume (=poweramp own Volume). But I will find a solution for this. If I can control the General Volume then it will be easy to also adapt the gap between the louder volume of the radio app compared to the Android Media Stream Volume.
Greets,
