Also - RSAP is a mixed bag - effectively your SIM card is virtually disconnected from your actual phone and connected to the car which has it's own cellular chip-set. This means your mobile is not connected to the mobile network any more, the car is!
Upshot is this is great for standard voice - most likely 2G - as the "car phone" used external antennas etc.... But useless for anything else!!!!!! You mobile won't have any data connectivity, SMS/Messaging etc and you end up with two call logs also
I use RSAP on the D4 as it is integrated with the navigation/google maps - it is bearable as there is a wifi hotspot in the car which used the "car phone" to provide data, so you an fudge by using wifi on your mobile to get some access. But even then, it is at maximum 3G speeds and tends to be cludgy.....
S4 & RS4 both have standard bluetooth, in some ways so much easier and no signal strength issues, with the roof down!!!!!
