Hello,from Germany,

 

This Post is translate with Google-Sorry my English is very bad

 

I've bought a F900BT EW on Ebay, and the same update to version 3.0202 and IGO8.3 cards goes gemacht.Es everything great.

But when I listen to radio and the ignition and then start making up, the radio goes on for 20 seconds, but then immediately switched to USB playback order ....

What is wrong??

Do I have to disconnect the USB flash drive?

 

Hope someone can help me

Nothing is wrong with your unit, mine does the same. I guess they are just programmed to select usb source first.

You can remove usb so the unit will select radio first, or just leave it connected then manually select radio.
