NAV and 6 disk changer in a Silverado

BBSilverado · January 4, 2005

I have been reading some your comments on adding a Navigation unit to various GM trucks and SUV's. I have tried some of the part #'s and they appear to be discountinued the changer in particular. asfar as rewiring is there more than the 3 wires to the remote changer?also is there a nonlux INR nav or its just the TNR ver. only?

There is a lux and a non-lux nav unit for both the INR and the TNR and also there is an INR model with its own internal amps for the non-Bose setup.

There are 6 wires from the changer to the headunit, 3 wires (audio left, audio right, and audio commom)that connect into the 12 pin connector and 3 wires (Power, ground, and data bus) that get spliced into the wires on the 24 pin connector.

If your adding the Nav unit then there is a VSS wire that gets added to the gauge cluster harness and ran to the 12 pin connector on the nav unit.

Ok… I went over this post and this is what I think I need…

I just purchased (Today) a 2004 Envoy XUV with the 1SC package and UB1 radio. I want to install the TNR…

What I need is:

10377287 nav unit

15135178 GPS Antenna.

If I want to use the other system I need

1037751 nav unit

15135178 GPS Antenna

Amp

Is this correct?

Thanks

The nav P/N's are the correct ones, but I don't know if that is the right antenna for your Envoy. That is the fullsize platform (Sierra, Silverado, Yukon, etc.) antenna, it will still work but it may not have the right mounting bracket on it for the Envoy's and Trailblazer's.

Is the optional UB1 radio one of the Bose system?

Thanks

Does anybody have the code and placement of where the vss wire goes (cluster-nav)is it a splice in on both ends?

The one end is spliced in behind the gauge cluster to the dark green wire with a white tracer, it is in position A4 on the gauge cluster connector.

The other end goes to the 12 pin connector on the nav headunit in the "E" position.

If you don't have a slave device (I.E. XM, Onstar, CD changer, RSA) then you won't have a harness that connects to the 12 pin connector and you will have to get a connector to fit that socket.

Looks great... I just started to get everything together for my 2004 Envoy XUV. I hope the GPS Antenna will work for my unit. Does anyone know if I need another antenna for the xm to work?

The XM and GPS antennas are 2 different antennas, The XM one is allready mounted on the roof if you have XM. The GPS antenna will get mounted under the dash pad behind the radio.

Hey on the y91 amp swap is it a straight swap or is there wiring mods to the harness? like the adding the 6 disc changer.

wcervin · January 7, 2005

I have an 04 Denali with Nav (bought it in September 2003). My system lets me select the 4 equalizer modes and midrange, but I haven't seen the noise-cancelling feature. Do I have the Lux version? I'm away from the car for a while and can't check for the Y91 code...thanks for any help

There are wiring changes that are made at the amp connection, plus the addition of a data bus wire.

The lux version should have 4 audio setting like: normal, driver, rear, and spacious. along with the normal base, treble, midrange, balace and fader.

The lux version also has a SOUND compensated volume whereas the non-lux has a SPEED compensated volume and five preset EQ settings plus a custom setting.
