Hi
My car 2010 E91 had a BMW-branded Nuvi 715, which stopped working. So I found another used non-BMW Nuvi 760. This fits in the same holder/cradle installation above the center console (sample photo), and the 715 routed the navi-voice + Bluetooth-phone calls through the radio. But the 760 does not. I thought that would be simply PnP... 
(It does charge and turn on/off with the ignition)
Can I fix that? Thanks
