What's the importance of rSAP profile?
I read the other day that the miss of rSAP cause problems on some Bluetooth audio wireless car kits.
My X2 works without a glitch on my 2009 Mitsubishi Lancer with a Parrot MKi9000 device. Also, the other day I've tried my X2 on a 2010 Audi A4 with original Audi factory Bluetooth wireless kit, no problems either.
Mitsubishi Lancer is NOT using rSAP (remote SIM access). It pair with you phone as a regular Bluetooth hands free - mean that even when paired, all phone calls are still received and pass thru your phone. rSAP is complettely different story and brings all new functionality and user experience. Via rSAP (google it if you want to go to more technical details) your phone "borrow" his SIM card ID to the car, transfer phone book, SMS and sometimes e-mails to the car so you can see/use them on your car main display/navi etc... and then phone itself switch off his radio and goes in stand by mode. What's the difference ? To make calls you are using car's external antenna, car's amplifier, and build in car audio system - as a result you get MUCH BETTER reception even in areas where network coverage is not good and CRYSTAL CLEAR sound. This is included (since 2005) in All premium quality cars/models of All car manufacturers. As example for sure is included in my Mercedes C-class (who is even "lower end" compared with E and S-class models). It is also included in BMW, Audi, Toyota (premium quality models only), Lexus, Skoda, WV (premium models and as an option for low-end models.
NOTE: rSAP Bluetooth kit is considered "optional" for Audi A4 as it adds premium experience - in A6 or A8 should be "standard" and included without need to order it as an option.
Anyone tested this? http://forum.xda-developers.com/showthread.php?t=372529
