I have been reading everything I can find on installing Nav in my 2003 Silverado with Bose Six Disc Changer. Most folks say it will work although the dealer says the computer won't work with the Nav. I have found a 15204334 Nav unit with 15135435 antenna I would like to install. There are a couple of things I don't know about.

 

Will It Work!

 

What is the difference between Lux & Non-Lux

If there a touch screen model that will work with my truck?

 

(Bose "UQ7 Speaker System)

Lux and non-lux are not interchangeable--The number 15204334 is a non touchscreen lux head unit. Lux only came in Denali's Escalades and earlier Hummers. I recently did a Lux conversion in my truck--Pretty easy--This thread from an earlier post will give you all the info you need--

Yes, it will work.

 

The thread from the previous post is very long but had everything you need to know.

 

I have the '04 TNR and love it.

Head unit #15204334 will not work in a Silverado unless you upgrade the amp from a premium bose one to a "lux" bose amp. It also is not a touchscreen--It is joystick controlled--Some non-lux touchscreen (that will plug and play in a Silverado) #'s are 15800000, 10379287, 10377287, and 15120706--Good Luck!

This week-end I am taking my interior apart :flag: to study the wiring system. After reading about the SP207, located above the glove box. I may try and develope a harness that is plug n play. I purchased a "Lux" amp (15191601) and am trying to find a good deal on a touch screen HU. Since I have a iPod interface I'm not going to install a CDX although I am going to do the wiring. :cheers:

Changing the pins on the plugs of the amp is pretty easy--You just have to be patient-Good luck!

Did you take your dash apart to install your GPS antenna? If so how did that go. Have you seen a copy of the radio schematic posted?

Yes, I removed my dash and installed the antenna--But I've heard of people wrapping it in bubblewrap and wedging it under the dash when you have the radio out. Removing the dash is easy, just remember the wires on the light sensor are short--

Is it possible to drive my truck without the radio and/or amp in it. When I take it apart, i'd like to be able to take my time. I read somewhere that the radio has to be installed for the truck to start.

Yes, it's possible. I have an '03 Silverado, and I drove mine for a month with no radio and no amp while I waited for the correct parts.

I gave it a try today. It started fine. Now I am trying to get my console out so I can remove the amp without drilling hole in the upper plate. If anyone has any tips on how to get the console out I would appreciate it. Tomorrow I am taking the dash top out (Waiting on my GPS antenna to arrive) Hope to have it all done in a coupe of days.

I've heard of some people using an ignition wrench for the front two bolts--I drilled the plate--Remember after removing the amp you have to remove the two little plastic tabs that snap into the metal plate and move them to the correct spot for the lux amp--The rear ones line up perfectly--I used a long narrow flathead ane pryed them up from the rear of the console--(Keep your hand on top of them while prying because when they pop out they like to fly!!)

      Tire pressure for 37s

      Do you think this width might affect the chalk test with a higher pressure closer to 65psi? I think lowering the pressure makes sense to get the tread to lay flatter

      My First Project and GMC has me stumped

      By asilverblazer · Posted

      I had an alternator fail that was shorted internally in such a direct fashion in addition to the larger gauge cables that it appeared like a VERY dead battery. Granted I think the car did power up, it definitely wouldn't start.   Rodent damage to wiring?

      Towing In Loose Gravel

      By asilverblazer · Posted

      Using experience to justify bad advice is lazy and typical of someone incapable of articulating why their advice is prudent.    This immediately sets off the BS alert and the advice that followed certainly qualified.   Asking an idiot for help getting out of dumb situations because he is an expert... at getting himself into dumb situations.   Unless I've been living in an alternate universe - the first thing everyone does when getting into a sticky situation is shift to a higher gear 🤨.   Of course not, the torque multiplication, mechanical advantage and finer control typically afforded by the lower gear is far better suited for this scenario.   There ARE scenarios where a higher gear MIGHT be appropriate determined more by the drivers ability to control EXCESSIVE wheel spin versus applying torque to the ground.

      I'm not sure I agree with "extreme" low speed, high torque sentiment here with regards to the prescribed use of low range. How about...whenever it's needed?   A 2.72:1 transfer case and whatever differential gears these Silverados have (3.42's, maybe?) aren't producing "extremely" low crawl speeds. Or insanely high torque multiplication. Even with the 1st gear in these newer transmissions. But it does provide mechanical advantage and potentially better control at slower speeds. And with extra weight or towing, I think it adds mechanical sympathy for the truck as well.   Plus, traction control and the other assists generally turn off when you shift into low range. Those aren't needed here, they'll work against you if you need wheel spin. In high range you'll need to figure out how to turn off the various modes those assists provide. Depending on the vehicle, those things don't all automatically turn off or turn completely off.   While I agree that a farmer might have some great practical experience, a recommendation to "always" using one gear isn't very informed advice. If the farmer had said WHY and could explain the physics behind his prescriptive "always" I'd definitely listen. The way he's described here makes it sounds like he could either be uninformed or is telling everyone what worked for him, not necessarily that there could be a more advantageous way about things.
