Default Mp3 unit

Hi, I bought a mp3 unit extension for my stock infinity radio, I linked it to the upper port in the rear of the radio but it doesn't work... any ideas?

OK here is the complete pinout but I am not sure if all are contained in the Crossfire radio. Think you are talking about the C connector.





Looks like you might be able to use pin 7 as control and 19-20-9 for inputs if they are connected.

The interface will work on the nav radio without the gps antenna being in place, but it will show an antenna error on the right side of the screen. You can buy a compatible gps antenna off of ebay for under $20.

This GPS antenna will work with the Crossfire (Becker) Navigation radio.

I believe, but don't know for sure, that there are differences in the European radio frequencies used, and I don't know about the GPS satellites. Most definitely you will need the navigation disks for your location.
