Hey Guys!

 

I'm getting a facotry Nav unit out of my cousins 07 avalanche that was just replaced under warranty, since he is getting some new aftermarket screen bluetooth monster of a unit.

 

i was wondering what is all involved on the dealers end to mate the new unit to my truck. a few dealers i have talked to around here have no flippin idea, and say 3 hours to do so.

 

any tech's input would be great so i can tell them what they should know already.

 

Cheers

If your truck has a amplified system its pretty easy , just add the vss/voice wire and the antenna and get the theftlock off and program it to your audio code in the glove box , if you have a non amplified radio you need to add a amp and the vss/voice wire and get the theftlock off .

UQA is what you are after on the sticker or UQA with Y91 , if its UQ3 or UQ5 it will sound like your in a tin can no matter who programs it.

If the truck has a Bose system, your dealer needs to program the radio as if the vehicle came with it from the factory - as montyss says, read the sticker in the glovebox to determine which options it came with.

 

You also need to add the harness (C4) that contains the VSS wire (pin 5) AND the voice output wires (pins 8 & 16). Voice output wires need to tie into the Front Left pos & neg speaker output wires if you want voice commands. If you want to add a camera, the dealer has to program the navi to accept it and you'd use pins 6 & 7 on C4. Click here to see the pin assignments for the outputs on the deck.

 

If it's NOT Bose, don't bother - you'll have to ADD an amp and it will still sound like crap. It would be better to do something aftermarket.

You must have bought a deck that came from a non-Bose vehicle. If you have a Bose navi, it requires a 4 channel amp. Also, you can get away without VSS and it will work, but map updating is slower and it may get glitchy in areas of low GPS reception (tunnels, tall buildings, etc.)

Hey thanks for the info so far.

 

The unit i'm getting is coming out of a avalanche with the bose system.

My sierra also has the bose system.

 

i would have gone the aftermarket route myself, but he just got it replaced under warranty and now he is going the aftermarket route and giving me the factory nav system.

 

all the dealers i've talked to say they get an outside company to program it.

 

If there is any techs that can chime in or can do this type of work in southern ontario, shoot me a message.

 

Cheers

If the VSS (Vehicle Speed Signal) is disconnected, can GPS addresses be entered while the vehicle is moving?

And would it also allow scrolling through the song list on the USB stick while the truck is moving?

I did that on my 05 Escalade and it worked on that radio. It made the radio think that the vehicle was not moving.

GM used to have Mass Electronics due radio stuff. Not sure if they are still doing it.

      Is 2027 GMC Yukon Getting a 682-HP Supercharged V8?

      By CaptPat51 · Posted

      Would you supercharge the 6.2L on a 2021 GMC Yukon Denali XL with ProCharger?.... 605HP is the stated number without going crazy - it's not the LT4 682HP package, but I'm tempted to install it... This vehicle was ... not... recalled on the engine swap - but I don't really know if that means ...don't do it... or do it;)    Maybe i should start a prediction market pool on it in case it blows up;)   Any thoughts appreciated - I already OWN the supercharger - stopped the installation when the recall was announced and now it's taking up space in storage until I can solve an electrical issue with the vehicle...  4th GMC suburban-equivalent truck - I like them a lot - when they don't a) discharge their batteries randomly, or b) throw a rod at highway speeds;)

      We tested the sleep mode with an ammeter in series with the negative battery terminal - 30amp fused - so we do know the actual shutdown and non-shutdown current draws and timing of the shutdown sequence.  We just have no protocol information to determine what module is issuing the network keep alive.

      Brake Pad Warning Message

      By Vu1can · Posted

      TrueBlue...Even if you don't have that info stuff displayed, If Mr. Computer thinks there's something you should know about, it will pop up a warning message no matter what else is being displayed. I keep the speedometer displayed all the time, yet the brake pad message pops up anyway.

      BTW, the 11.5amp draw is all the usual systems active - it's not a single draw - that's the "we're all awake" state of the vehicle - forinstance if the power steps are actuated, the draw will spike to 22amps for that operation.  when the battery is disconnected and then reconnected, the vehicle shuts down that one time only - and we see a 10-15minute progression down 11.5  10.5  9. 8 6. 5. 1.6... 500ma... and then off to sleep at 40 milliamp... as expected.  So we know it's a module that is simply refusing to allow the SDGM to proceed to the sleep state.  We do NOT think it is the telematics VIM module - since we already duplicated the problem with the "VIM bypass" solution installed (we reverted that since it also disables the gmc app - but it does not appear that the telematics system is the culprit).  We've replaced the rear heater control module, tested without the wireless charger, and the other modules on CAN Bus 5 - but still something is keeping us awake and removing X2 from SDGM allows sleep to proceed.  We cannot diagnose from OBD since OBD drops off at about the 9volt level in sleep mode and we can't communicate with the vehicle - also we can't trace the SDGM internal packets from the OBD side - we have Autel Ultra.   Any ideas on why disconnecting X2 would allow sleep to proceed appreciated.  This is no longer a repair situation - this vehicie is simply unusable in this condition and NOBODY at GMC Dealer can even understand what it is doing.  This is crazy.  We made these systems too complex and now we're paying the price.

      Did this ever get solved?   I'm chasing 2021 Yukon Denali electrical issues - vehicle will not enter sleep mode - we can disconnect and reconnect the battery and it will sleep - but that's likely because we powered down whatever module doesn't correctly sleep.  once we start/accessory the vehicle and turn off, it will stay at 11.5 amp draw with something keeping the SDGM alive - it appears to be activity on the X2 segment, specifically CAN FD Bus 5 - but we don't know which device and we think we've already isolated all of the devices on that segment - so what keeps the BCM and/or the SDGM alive is unknown.   I don't yet have a packet trace from CAN 5 (and since this Global B we might not get much info from it) - but the vehicle has been down for 8 weeks and previously GMC Dealer was unable to resolve "kills battery" issues with this particular vehicle - so I'm at a loss - it seems to be beyond local repair capabilities - and the number of "telematics keeps vehicle from sleeping" posts indicates this whole architecture has major issues - I hate to say it, but we might have to install a battery cutoff switch on the front grill - one of those red boat switches - to turn off the vehicle.;)  Any pointers appreciated;)  I just bought a CAN FD interface and I'm planning to try Savvycan and Peak Can SW to triage this further.
