Installing factory Nav in an 05 Sierra 2500HD Duramax

[duracam]

Ok......bought a Factory Nav head unit on ebay thinking it would be plug and play however, it has an extra plug. Simular to the one you find on say, your computer monitor, printer, etc. with the securing screws. No idea where to plug it in, and can't seem to find any info. Plugging in the 2 plugs that do match up and turning on the acc with the key, does not bring the unit to life. Anyone............???

You probably have a luxury head unit.

Actually beyond a security relearn the correct head unit actually is. My smart phone did away with any desire for in dash navigation lol.

Possibly........there was alot of great info on that link. Thanks for that. The link didn't have any info on that third plug???

[Badass69]

Can't tell you. I want to someday add the luxury amp and deck to my 04's Bose system but I just want the regular deck. That said I need to get the deck and amp for nothing because if I have to pay what people ask on the net I may as well buy some real aftermarket components. Even a GM nav system for a 2013 would tell me the roads I am driving on don't exist lol. Google map however shows everything just fine.

Post a picture of the connector in question. I have dealt with numerous radios and have never seen this connector. It sounds like you have an aftermarket radio.

I thought the navigation from that era had three plugs. One for the speakers and power, one for rear seat controls and one for both the vehicle speed and GPS antenna. That may only be for the non-lux one though.

That's not a VGA output for rear seat screen? I could be way wrong but just a thought.

[MikeNH]

Did those decks have a slave drive for the map disc or anything? I've never seen one in person so I'm guessing here.

That radio doesn't play regular DVDs from what I understand. The Rear DVD only pumped in audio to the head unit as an aux.

 

After digging I found this thread on another forum: Performance Trucks.

 

On that page, see number 2,3, and 4.

 

In short, GM makes two different Bose speaker systems for the GMT-800 series vehicles: The Bose “Premium” (non-lux) and the Bose “Luxury” (lux). The non-lux system is what you get with an SLT/LT Silverado/Sierra/Suburban/Yukon/Yukon XL/Tahoe. It utilizes a mid-range speaker in each door, a tweeter in each A-pillar (the tweeters are wired in parallel with the front door speakers, and they are given a capacitor to act as a high pass cross-over) and a 6.5” dual voice-coil subwoofer mounted in the center console. If your door speakers say “Bose” on them, you have this system. SUV’s also have a speaker in each D-pillar as well (these mid-high range d-pillar speakers are wired in parallel with the rear door speakers on the NON-lux systems and on the LUX systems, they are wired into a separate channel on the amplifier, so they can receive different signals than the rear door speakers). Now, Denali’s and Escalade’s have the Bose
“Luxury”, or [RPO code] “Y91” Bose speaker system. The great part is that the speakers themselves and the subwoofer are IDENTICAL to the non-lux system. Both non-lux and lux Bose speakers are referred to as [RPO code] UQ7 on the build sheet and in your glove box sticker. The ONLY lux/non-lux difference is the AMPLIFIER. And what a difference it is! The Luxury amplifier is of MUCH higher quality and also has more RMS wattage output. It deals with sound completely differently than the non-lux amp and processes it in a much cleaner fashion, for MUCH better sound quality. It also devotes much more power to the subwoofer, so with a Lux system, the sub is actually woken up and makes itself heard. Now remember, this is still the same 6.5” sub, so it won’t blow out windows, but I bet it will sound much richer and deeper than you ever thought a 6.5” sub could sound! The Lux amp is also fully computerized and utilizes an onboard DSP (Digital Signal Processor, or Digital Sound Processor; I’ve heard a DSP be called both names) to tweak the sound and also provide different sound field/reverberation/environment settings, such as “Driver”, “Spacious”, “Passenger”, and “Rear”…it is a “Smart” amp. The lux amp also is fully integrated with the vehicle’s Class II data-bus, so functions such as muting and control of the amp are all done via the BCM (body control module… basically the cars main computer) and Class II data. The non-lux amp is jokingly called the “Dumb amp” because it lacks any computer or control of the sound. The only thing it has is a simple passive crossover to prevent high range signals from going to the sub. So basically, that’s the difference between, for example, an Escalade Bose system and a Tahoe Bose system… a 600 dollar amp versus a 170 dollar amp.

 

Non-Lux Amp is traditional amp that amplifies the audio signals from the head unit.
Lux Amp is a smart amp that uses the class 2 data bus to send audio signals between each other, using a full on-board computer and DSP (digital signal/sound processor) which optimizes the sound much better. And you can program a lux amp for which vehicle it is in and it will alter the sound processing sequences to make the sound perfect for the size cabin! (for example, it is going to have to be programmed differently if it is in a larger cabin Escalade ESV versus a smaller extended cab Sierra Denali (that’s the only truck that gets a lux amp from the factory...if you don’t count the Escalade EXT as a truck

Unfortunately it sounds like you got a LUX unit and don't have the amplifier.

[rusty503]

Ok, now I understand. What you are showing is an aftermarket addon. It is either the GM Lockpick or a video interface to add a video input or backup camera. This is NOT standard from the factory.

 

Look at item #180831961465 on eBay for an example of what I am referring to. Now look at item #271224815761. While not the same exact part number the back panel IS the same. Note no additional cable and connector.

 

I would contact the seller and see if you can get the rest of the setup. Otherwise you will have to unmod the radio.

[rusty503]

I don't think not having the rest of the setup will prevent the unit from powering up. You may have other problems. The only way to know for sure right now is to unmod the radio.

[Chris]

If it is a LUX tuner which it is, it had the auxillary CD changer

[Badass69]

Not to mention a lux headunit is useless without the amp and will never do anything. Send it back and get the correct non luxury one or sell it. Either that or get the lux amp and follow the writeup I posted from pt.net that explains the luxury conversion.
