My 3 year old unit is now facing a new problem. I used to have an iPod touch that used to worked fine with this unit couple of years ago. I recently bought an iPod Nano and plugged that into the unit.
The issue is that the F700 doesn't recognize it when I start my car. I have to disconnect it and reconnect it to make it work. I even tried my iPhone 4s. It has the same issue. I don't think there is any loose wire - the iPod never disconnects when I am driving.
I searched this forum but couldn't find any answers.
