I am about to add the LUX touchscreen Nav radio (and 6-disc slave CD player and LUX Bose amp) to my 05 Tahoe, replacing the stock unit (with built in 6-disc CD). I have read numerous articles, but wanted to see the total wiring diagram. I have posted six images in my garage that contain the full diagram. Print them out and tape them together (3 across in 2 rows) and you can see the full vehicle diagram for the LUX install.

 

I have attached one of the shots to this post so you can see what it looks like...

That's what I am going to do, but for me, being able to visually see how everything interconnects makes it simpler...

 

I have already pulled the dash and added the GPS antenna, snaking the plug end behind my current HU. My biggest problem is finding someone with a Tech2 to do the VIN relearn on the new Nav unit: my local dealer wants $130 for this 2 minute procedure!!

Ok a couple of things you need to know

 

You have to run a connection to the SP207 to connect the AMP to the class II Bus

The Lux system uses a little mic is the drivers side of the console to hear noise in the cabin to adjust the volume

 

Let me know if you any questions

 

What state are you in I know a guy who can unlock it

I pulled down a ton of information from Diesel Place, and have read till my eyes blur. I know about the Class II wiring issue. I bought my Lux amp off ebay, and the seller included the mic. Already tapped into my VSS wire, and added a switch to the dash to allow input while moving...

 

I am in San Jose, CA.

The guy I know is in Michigan, I feel your pain about the blurred eyes.

 

But it's pretty simple to repin the harness and plug everything in and off you go.

You would believe the difference in sound quality with the stock bose speakers

I have not had a problem with the 'Premium' system, but am looking forward to even better sound and being able to toss all my paper maps. I got the HU and slave CD from a guy on Craigslist who had upgraded his Denali, and had the units sitting in his garage for the past year. About 3 months of use, and I got both for $380...Looking at what they go for on ebay made me very happy! :flag:

Thanks, I appreciate it.....

 

The amp came out of an Escalade, so I know the cabin configuration is the same, so I won't have to have the amp touched. Also, when I got the amp, he included both connectors, so I have been able to practice the pin moving before getting to the real deal!

 

Did you to the VSS interupt and how has that worked for you?

It was an easy splice, and I used a GM Auxiliary Light switch on the dash (next to my traction control switch) to keep the stock look. I will let you know if I run into any problems...

I just finished the amp/hu swap...boy was it easy thanks to the directions on this site! Everything went as outlined, and I cannot believe the sound difference!

 

The local dealer wants $130 to unlock the nav radio, and they can do it next Wednesday :thumbs::nono::cool:

 

I have found a local independent shop that has not done it before, but has the Tech2. He said that if it is easy to unlock as I told him, it will be really cheap... Will find out tomorrow!

Went down to the independent shop this morning...he has a mechanic who worked for a Chevy dealership for a number of years. I showed them the steps to release the VIN lock, he hooked the Tech2 up and within a minute it was functioning perfectly!

 

The best part was when I asked how much, the manager told me "we learned something new today... Happy New Year!"

 

I think I will drop a gift off there Monday morning! :fume:

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      2020 Trailboss 6.2 replacement

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      2020 Trailboss 6.2 replacement

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
