NAV and 6 disk changer in a Silverado

godav · March 5, 2005

I Have just finished installing a Nav system in my 2004 ext silverado, I have a 6 CD Changer I want to install. I have read every post in this tread and I still need some help. According to the diagram (9 pin to 12 pin Aux cd harness) I need to soldered 3 wires to the 24 way harness (the Dark green to A1, the Orange to B1, and the Black to A12). OK here is my first question, is this to be done at the raido end or the Amp end? Next the diagram the wires going to the 12 pin harness at the raido ( Tan to K, Brown to J, and Light green to H) OK heres my second question, do I remove the existing wires in the 12 pin harness or do I solder these also.

Any advice would realy help

Thank Ypou

I connected data to A1, all my connections are soldered and shrink wrapped, I checked wiring multiple times, and took my time...I'm in no hurry for screw-ups, for whatever it's worth...

Sounds like you did a good job, I would have to put my money on a failed or failing AMP, or a failed or failing HU.

Make sure that your pin connectors are not backing out when the connector is plugged to the amp. Remove the console glove box and and the rear of the console, turn on your radio and push the connector and see if anything changes. If you get sound you have a weak connection on one or more of your pins. This happen to me for one speaker when I did the swap, had a pin not staying in place when connected. Hope this might help anyone who just lost sound or it comes and goes.

Hey, i have a quick question. is there any wire on the back of the radio that is 12v+ only when the radio is on?

Yeah just cut into them and solder them. I had the same problem. I have a silverado ss with xm radio. I did that and everything works great.

Great post! LOTS of information. But I have a question about the VSS connection.

I'm planning to purchase a non-lux TNR for my 2003 Yukon and and was wondering if anybody knows what the VSS is actually used for? Is it just to let the nav system know that the vehicle is moving, or that it is moving a certain speed?

One post around page 12 or 13 mentioned adding a bypass switch to temporarily disconnect the VSS which would allow you to program the nav while moving. What I'm wanting to see is if there's another way "trick" the nav into thinking the VSS is connected, but still be able to program a destination without adding a switch.

If the nav uses actual vehicle speed to compensate for slow GPS updating, then this is probably not possible. But if the VSS is actually a discrete of some sort, then it should be able to be bypassed. Anybody got any ideas?

Thanks in advance for the info.

The VSS helps make the navigation faster and smoother, thus adding accuracy. It also keeps the nav working in low or poor GPS signal areas. Adding the switch is only needed if you want to be able to change or add destinations while the vehicle is in motion.

This is definetly true. Before I had the VSS wire hooked up if I would be driving real fast it would say take next exit 1/4 mile and I would already be at the exit. It works a lot better now.

I just finished my install of the navigation unit/amp and most everything works great. I am taking it in tomorrow to have the Theftlock unlocked. The only problem I have is that now the RSA will not work. Is this a common problem?

nothing should work till the theftlock is unlocked, but all should work with the key in the acc position, the theftlock is not locked up untill the key is in run position

Hey, Im helping a friend install an amp an subs tommrow, for the LOC should we tap at the radio or rear speakers? This is a non bose 2003 silverado. ext cab. I would prefer to tap at the radio. i also heard that the rear speakers do not have enough bass to tap there is that true?

also, if i tap at the radio, tap the front or back speakers?

If it is a non-Bose then you can tap at the headunit, and use the rear speakers.

your correct that the rears do not produce as much bass as the fronts, but thats i because of the speakers design and has nothing to do with the signal going to them.

Thanks, I guess I'll just add the VSS switch.

Also, I didn't see too much info on the Rear Seat Audio in this thread. If I'm adding the Nav and CDX to my Non-Lux Bose system, is there anything special I need to do to retain the RSA? Is the CDX compatible with RSA as well? Thanks.
