I have bought the WLAN HOT SPOT Snap-In for my actual 525d which seems to have the same feetures as the SAP Snap-In but brings a WLAN HOTSPOT with it.
Anyhow I am only interested in rSAP for telephone function with my Samsung Galaxy S2. The Samsung Galaxy S2 has already implemented rSAP but as it seems to work with Audi and VW it doesn´t with BMW (but the HOT SPOT works alright with the Nokia X6).
With the Galaxy S2 it connects via rSAP but shortly after this confirmation in the S2 the HOT SPOT disconnects
Once having a Samsung App ready may be it works for S2 and BMW as well?
