Hallo and welcome!
I have a problem with connection of my Samsung X-cover2 (GT-S7710) with my car bluetooth VW premium module (5N0 035 730 A).
Only reason that I buy this phone was full compatibility with r-sap application but something must be wrong with configuration.
Phone was rooted according to this manual: http://forum.xda-developers.com/showthr ... 889&page=5
Then I checked trial r-sap app with success - phone connect with car and phone book works also..
I removed trial application an buy full version and phone can't connect with car until I restart main application (uncheck and check 'rSAP Active') or make again Install/Update System Files in rSAP Installation App (v2.4.3) - after that it works good.
I choose Standard rSAP Installation in Installation APP.
From the car perspective:
Very long time "connection.." on car dashboard, then "initializing.." and finally "cant connect..."
From the phone:
Bluetooth State - connected
SIM State - SIM access
but network state looks normal not like disconnected from network - this happens sometimes, not always.
What do I wrong, something missed?
