730n upgrade issue
So I just upgraded to the 730n from the 430n. I needed the built in traffic. Anyway, after the update, 2 things still persist. 1 - the USB drive in my armrest doesn't work. 2 - on phone calls, every so often there is a garbling or ringing noise when I'm on the call. I had to have the uconnect wiring harness installed up to the mirror since it was a stand-alone feature with the 430n, rather than being integrated in the 730n. Any thoughts or suggestions?
