OK after being going nuts with nothing to do I went in the garage and pretended I was on a road trip and it was sunny and 75 out and I plugged my phone into the cassette adapter on my 85A and found out I could use the phone through there, now for my question. I have a smart phone (nokia E5) and have no desire to use the phone while riding but if I were using the GPS on the phone could I play music and the GPS at the same time, through the phone of course. I am not real smart with these phones up until this point I really only use it to call or text and maybe a picture now and then. Is anyone else doing this now ? I think that would work and it is nice with the sound coming through the speakers.
