Ok, thanks for replying, next question then. For the time being, i am just going to get the HU #15229287 or equvilent. Besides the antenna and disk, is the unit plug and play? besides getting the techII thing done on a used unit. 

If I buy a new unit, there is no need for the techII correct?

Thanks all,

Amos

Yes, the unit is plug and play if it is a new one, you will have to add a wire from the gauge cluster wiring connector (dark green w/ white tracer in A4 position) to the 12 pin connector on the headunit to the "E" position. The wire is the VSS (vehicle speed signal) and it is only needed for the navigation function. The signal helps keep the navigation working smoother by providing a speed input when the GPS signal is weak.

I am new to the site. I have a Z-71 04 Suburban and I added the the NAV unit 15229287 with GPS antenna 15135178 and do not have the disk yet so could not try it. The 4th dealer was able to unlock it finally. The first three were clueless.

 

QUESTION: Will I need to add in the speed sensor wire as well or is it in the cluster of pre existing wires? If so are the instructions the same here as above?

 

I cannot currently look at the truck wiring harness since I am away at work in China right now for a month.

The VSS wire is not there, you will have to add it. Same procedure as posted

Thanks and was worried that the answer would be that. Does the wiring harness that plugs in the radio, 12 position "E", have the metal connector in the plastic or do I have to find one? If I need to get one, where do you get it? Also do you by chance have a Diagram of the where this all plugs into. I don't want to mess up plugging the wring thing since I really don't know what is pin 12 and "E" connector. I would love to look now but I am in China.

 

Thanks Darryl

This is the C2 (12 pin connector) on the back of the headunit. The VSS wire will go into the "E" position and you will have to get a terminal wire end.

These are the terminal wire ends, GM number 12089649 that is a bag of 10.

This is the connector on the back of the guage cluster. You splice into the wire in the A4 position (marked as the green with white tracer) and run it over to the headunit's C2 connector and install as mentioned above. The best way is to strip a little insulation from the wire and solder the new wire to that and then tape it up good, or a crimp-on wire tap can be used.

Thanks very much. I was unable to see the pics you added in. It appears the sites the pics are being loaded from may not exist or since I am in China, the government filtering and is not allowing them through. Can you email me the pics. My email is [email protected] and maybe my work email to so I am sure to get it this time.

 

[email protected]

 

Thanks for all your help. I will be back in the states at the end of the month and will get right on this to make it all work.

I keep seeing refrences to the Cell Phone connection, but does anyone know where to get one or how they connect?

 

Everything on mine works and sounds great, and Seller is going to fix the Rom drive for me. :ughdance:

Sierra Denali would be a perfect match for you, If you have a TNR use the 05 model year and if you have an INR use 04 for the model year.

I haven't messed with the cell connections but I think when you buy a cellular car kit for your model phone it will have the wires and directions for connecting to the headunit for muting when a call comes in and when it is in use.

I have a Lux amp out of a 2003 Hummer H2 for sale for $250.00 I decided not to do what I was going to because I would have to change out the HU, don't want to do that now. There are cheaper ones available on E-Bay I hear but I have not seen them. If you can get it cheaper , have at it. I gave more then $250.00 for mine because I was all fired up ready to go and found it at G&R over in Oklahoma City, they are proud of their parts. :thumbs: This one is part # 15199884 . Please make sure it will do what you it to first.

I just got done reading all 27 or so pages. This thread has tons of great information. Thanks to all who have contributed!

 

Now my quick questions. I haven't seen these brought up yet, so I hope I am not asking a redundant question.

 

1) It seems like I heard the new touchscreen NAV units play MP3 cd's, but the older non-touch screen units do not. Is that true, or do neither play MP3s?

 

2) Besides possibly MP3s, and obviously having a touchscreen, are there any real differences between the two? Functionality or usability wise?

Can't say that I've heard of a TNR that can play MP3 CDs...and even if it could, think about what happens when you need to use the nav function, since it requires the nav disk to be loaded in order for the nav to work...

 

No other significant functional differences between the two, other than the obvious...well, not unless you include the fact that the TNR has a slightly-larger screen than the INR.

So if i decide to go with the touchscreen nav system and don;t get the six disk changer, then I won't be able to use the navigation system and play a cd at the same time??

none of the current nav units will play MP3's, neither will the slave 6 disc changers.

The new Hummer H3 has a headunit that will play MP3's but I haven't seen one yet to know if we can upgrade it in our trucks.

My wife's 2004 Saturn VUE has a 6 disc changer HU that plays MP3s. It's amazing that the 2005 nav HU which was just came out doesn't.

 

Can anyone reccomend an AUX adapter to convert the CD changer/XM inputs into RCA so I can hook in my mp3 player?

 

I have seen the PIE GM12-AUX be a good choice?

Do you have XM or the changer? most of those input adapters will require you to have one or the other, and some will not work if you have both.

That is correct, the mapping DVD must be in the player for the navigation to function.

      Blend door actuator

      By Charly · Posted

      Trying to replace the temperature control, blend door actuator in my 2005 GMC SIERRA 1500, but can NOT get to it by just removing the under panel on passengers side. It seems like I will need to remove the side panel of the center console, or the entire center console just to get to it- can anyone offer instructions, pictures, videos… step by step so I can get this done!??!! It’s TOO HOT to be without AC!

      I am new to this… but I saw some of your replies to another person doing the same as me… trying to replace the temp control actuator in my 05 GMC SIERRA, And can NOT get to it… how do I get the center console panels off, do I have to take ALL of them off to get to it? 80481681120__F97CE005-C5E5-4FBF-9589-1388214E3586.MOV

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By marpel · Posted

      Although there is a "recommended" weight by those who sell trailers, my experience has been that they are way too aggressive in their information, for me at least. My '22 with 6.6 Gas, has a payload of about 3400 lbs and depending on your specs (I don't have 4WD so it has a bit higher Payload than others) yours will likely be different. Payload is one of the most important numbers for towing. Although you "could" tow the max trailer weight for your truck, I, personally, would not go close to that number. Having said that, a lot depends on how/where you will be towing. I live in the LMD of BC and often tow to Denver, Co, along interstates (flat and mountains) and I find I need to keep it in 5th (6spd) for the trip and travel at around 65mph. This is for a trailer dry weight of just under 3500lbs. If you are only doing local, short trips, it would not be that big an issue if you had a heavier unit. You will be surprised how much stuff you load the trailer with, so I would only recognize the trailers "full" GVWR weight rating, then decide on the appropriate trailer from that number. If you are worrying about how much stuff you should be putting in a trailer, you might have too large a rig from the get-go. Once again, depending on what terrain/distance in which you will be pulling. Marv

      Disconnecting Battery

      By marpel · Posted

      davester, Thanks for the response, how ever, I think I am now a bit more confused than I was before I posted - - After I posted, I actually found a YT video of a guy who replaced his Module (above tire) and he only disconnected the ground cable of the battery, but you describe rubbing the two cables together after disconnecting. I presume that is to do as you describe and eliminate any residual energy? - When I picked up the Module (between my posting and reading your response) from the dealer, I specifically asked about any re-programming and he stated it was not necessary as it was simply plug and play. Don't know how knowledgeable he is, though. - The video I watched also showed the Module plug to be difficult to "unlock" and remove, but there was no mention of silicone, although the video did show a bunch of dust/dirt in and around the plug (old truck) during removal. Are you talking about silicone that was applied by the factory, or silicone that you applied prior to plugging in? Thanks again, Marv
