Is it possible to get Ericsson T39 phone to work on X5 2005?
 

I have this old phone, which works fine with other BT devices. When I pair it with my BMW, I get prompted for the passkey and my phone gets paired. However, when I press the Phone button on BMW, it says "Activate phone"... Any ideas?

It should work. It worked fine with the pre-2004 Visteon BT module

:dunno:

it was tested on my post 2004 car. it works.

there is even an snap in adapter available for this model. so deffinitely should work on any X5 imho
