I purchsed my car (2006 C2S) used about a year and a half ago. It came with a Mobridge unit. My iPhone 5 will not connect via the BT so I figure I need to update it. Does anyone have experience with this?

I have tried the Mobridge updated via BT which has not worked. My BT dongle sees the mobridge headset but the mobridge updater wizard cannot find the BT dongle in the computer. If anyone has suggestions on how to get it to work that would be great.

I really don't feel like tear apart the car to access the SD card slot. It that is next. How big of a deal is it?
