ford navi in 09 f 250

Hello, I have a 09 f250 fx4 with ford 6disk changer,sync and sirrius. only have 4 speakers ... I bought a NA6W-4200GB Navi(FORD NAVI) from EBAY, Everything works except for sound... Can some one please give me a few ideas here? thank you,

So the Factory wiring just plugs right in right? Check the factory amp turn on wire. Amp Turn On          VIOLET/RED          (+)          RADIO HARNESS      It should read 12V.

yes thats correct...plugs right in... i will take a look at the amp wire... but are you sure that my truck has a factory amp? how can i tell? thankx again

any idea where i can find the amp in this truck? if it has one?

Take a 9 volt battery and connect 2 foot wires to it, then touch these to the the speaker leads on the radio harness. If they pop there's no amp(which i'm doubting there is...)Mike M2

ok thank you, can someone email me the partnumber for the factory amp?

ok nevermind about the amp... i spoke to the dealer and they said it needs to be programmed for my truck. My local ford dealer does not do any radio programming. does anyone know where or how i can get it programmed??

Ok well got everything to work... here is what happened... 1. 09 Navigation System does not have a built in amp and needs a factory one otherwise the speakers will sound like s**t 2. You can get the amp from Radios and More they are awesome. They even walked me thru where the amp is suppsed to mount 3. Radio might need to get Programmed for some features(like voice commands) to work. Dominic From Arc can do this for you. All in all very simple once you have all the parts
