:hmm: The basic installation for the DVD NAV is super simple. The hardest part is removing the instrument cluster to tap into the VSS wire. If you have "basic" skills, you can do it. Read, reread, the FAQ on the radio swap. Follow the steps. I would highly recommend the seller for the NAV unit you're looking at. I purchased mime from him. He's sold many to forum members. Don't ask the dealer about installing this. First answer is "can't be done'. They don't have a clue. Cut out the less informed. Any audio installer could do the swap with the necessary items and the detailed instructions provided on www.cadillacfaq.com There are two phases for the DVD install. Phase one is without the additional wiring for "voice guidance" and "voice commands". Start with phase one. You can add phase two later. Chances are you don't have XM satellite radio. If you go with the NAV, you might want to install it at the same time. Check www.radiosandmore.com for their XM kit. I also put a 2005 DVD NAV in a 2003 CTS, no problems. I don't believe there's another mod for your CTS that will give you more satisfaction for the money. DO IT!dslplaya said:Hey guys, i found the nav i want.
The only problem is after reading the facts, it seems like its to technical for me to do it. Do you think a dealer will install it? or a place like car toys maybe? I want it to be just like stock and have all the voice commands to work too. Keep in mind i have a 2003 cts, this 2005 dvd/nav will work in there correct?
IS there any chance the VSS wire is already connected. i thought i read somewhere that on 05 models it was already in the harness. anyone with any experience with this.odysseus said:The C1, C2, and C3 connectors are pinned identically, whether you have the Base, Bose/DIC, or Nav. The only difference is the Nav adds connections for the VSS (required for the Nav to work), audible directions to the Bose amp, and the voice commands going to the VCIM (On-Star box). The last two are optional, since those features will simply not work without the harnessing.
You'll need to add all of those, if you want those features with a Nav, except there is no provision for the audible directions (nav talks to you for turns, etc) for the non-Bose amplifier. On-Star and the cell phone will work identically, but you'll need to add harnessing if you want voice commands (talk to the nav to tell it what you want to do).
I haven't installed a Nav into the base CTS, but from the schematics, this is how it works. Anyone who's actually done this particular swap can chime in.
You easily just add the address using the dial. As for gas stations etc. you just choose gas station in the destination menu and it will list them in the order that is closest to you.rm2077 said:i am not very fimiliar with the how the nav functions. how do you imput lets say an address or gas station without the voice commands? i have never actually got to play around with one.
