.. A great phone. So to get you started. But unfortunately: I have the Galaxy Ace 2 added myself to pair it as secondary device with the FSE my Passats. And just that is not possible. Interestingly, the coupling work with my Galaxy S3. In addition, the devices (Volkswagen UHV Premium and GT-I8160P) recognize the coupling attempt via Bluetooth. But then a message is displayed, after which a coupling is not possible. The argument mangelner Android support I exclude, because the coupling works very well with the S3. Maybe it's the company policy, more high-end equipment for sale? It will probably be opportunities to strike up special rSAP Apps on a mobile gerootetes. That it can not ultimately be. If there is no solution, I'll return the phone back. The support is so far no real help. Phone support even the recommendation came with the device first of all * 2767 * 3855 # to be reset or zuzulegen another S3. When VW was even alleged that to couple the S3 with the UHV Premium, the chance is 0.01%. Since I'm so times really lucky :-) Slowly I start to doubt what it is the protocols rSAP and HFP ....
