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

Steve

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.

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

 

<{POST_SNAPBACK}>

 

 

 

 

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.

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

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.

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.

      Because that is IDIOTIC, much like this question. They've already been forced to do it by past administrations - why would you roll that back when it's a GOOD thing?  WHO IS ARGUING FOR LOWER MILEAGE???? 😂  NOBODY IS!!   I'm certainly not! What I want is RELIABLE vehicles again that are worth the price paid!    I don't get your logic here ...   In 2003 I paid $2,200 for our '86 Grand Marquis. It's STILL running and I've never been inside the engine, aside for the timing cover since it was leaking, so I threw a new timing set in since that makes sense. Transmission is ORIGINAL. Electric pump in the gas tank is ORIGINAL. Rear end is ORIGINAL. I'd have to hit my head REAL hard to want to pay $60k or more for a car that still can't come close to the comfort, seating and storage space, or reliability of this one. Nothing is even in the ball park! Hundreds of thousands of brands and models have been built and sent to the crusher while this one keeps on going!   https://postimg.cc/Z9XRrCSg   I've got a whole fleet of cars, motorcycles, and a truck close to this age for summer and winter. No one could pay me enough to buy anything built this century. I have zero use for any it.

      Since I'm the one who has to fix them when they break, I'll take vehicles over 30 years old all day, EVERY day, over ANY modern crap. Have you attempted any repairs on anything built after 2006? It's a friggin nightmare, and gets worse the newer the model year.    If I had the will or desire, I can make any car of any age outside of a Model T (I don't have THAT much will ...) just as powerful, comfortable, and have all the tech the new stuff does, and get pretty close in mileage, too. I prefer SIMPLICITY. The less the vehicle has, the less to fix WHEN it breaks, not IF.   I'm glad you snot-nosed punks don't like them. More for us, plus that keeps the prices from climbing more than they already have.👍

      Bringing this thread back on topic. I just noticed the incredible lack of bright chrome across the entire new lineup. Even the Denali has tinted the brightwork in the grille and has none elsewhere. None of them have chrome bumpers. As far as I can tell there aren't even chrome mirror caps. I'm curious if this also happens out back? Are there no chrome rear bumpers either? This is quite the departure for GMC.
