First time poster here. So I bought a bluetooth car kit, that attaches to my visor. It acts as a bluetooth microphone and speaker when making phone calls. The only problem is that the speaker on the device sucks, but I am told the mic is very clear. Does anyone know of a way to force my phone call audio out my Razr's 3.5 m jack so I can hear my phone audio out my car's speakers, and still keep the bluetooth mic working? thanks in advance.
