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?

 

What "upper port" ? I had to replace he head unit on mine to get BT/USB.

 

The port above the one used by the stock connector... what do you mean whit replace?did you change the radio?Is not possible to manage mp3 unit with stock radio?

 

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.

 

ok i surrend, the stock non nav radio doesn't manage mp3 unit, only the nav can...so I'm searching for a nav unit but what if i install it without the gps antenna?obviously the gps doesn't work but cd and cd changer (and so the mp3 unit) does?

 

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.

 

good...can you show me wich?
I only must connect to the radio by his port?

 

But a us unit will take signal in Europe?

 

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.
