I have just completed the Nav conversion on my 03 with Bose Lux amp.

If you don't have the Y91 or Y92 option in the glove box, then I am pretty sure you need the non-Lux nav unit for your Bose radio system.

Once installled you need to take the truck to the dealer, to have the VIN re-learned with the Tech II hand held computer and should be good to go.

You will loose the 6 disc CD dash player so you may want to think about a remote CD changer or the PAC interface for MP3 players and use the Nav unit's XM/AUX input to play the iPod or any other player.

I used a RF converter in mine and connected a Sony 12 disc CD player and also the XM/AUX interface to feed the audio from a DVD player that runs both the overhead LCD screen and the NAV screen video adapter. This way I get video on both monitors and the audio on the Bose stereo.
