Navigation Installation


Recommended Posts

Posted

I just hooked up a Navigation Unit on my 07 SIlverad (LTZ Package, RSE, Bose Sound you name it I got it). Installation went fine. Had to take to dealer to get system programmed. I now have no OnStar or XM. Any help I could get would greatly be appreciated. Part #on Nav unit is 15940102. Any help would be greatly appreciated. :cool:

as far as XM you may need to call them so that they can update the SID number for your new radio. As far as OnStar I have no clue.

Thanks for the reply. What has me baffled is there is no XM tab on screen. Navigation. AM/Fm, CD & DVD are working. I will try what you recommended and keep posted my replies.

Try double checking the plugs in the back of the Headunit it my be loose.

 

 

That was my first thought especially after I got back from the dealer and they has the ""THEFT LOCK"" message removed. They got everything up and running but couldn't get ""static out of system"". Got home and guess what, the attenna wasn't plugged in all the way. After closer examination of unit I beleived I received a non xm/onstar capable product. Talked to seller on Ebay and they are to send me the right one next week, Which will be fine so my wiring from JP customs will be in. Look like I got another weekend project. Will keep updates. :uhoh:

My understanding is that when replacing a radio with another, the XM must also be programmed at the same time by the dealer. Otherwise, the new radio will not have the XM connected to it by the software.

:lol: Got my replacement Nav Unit installed. Went to dealer and they reprogrammed it for me. Technician was even cool enough to let me watch. Installed a Loc Pic so my wife can watch a movie while I enjoy the comfort of my SILVERADO! :lol:

read some other threads about this..do you have the vss wire connected as it seems if it is not you will have no onstar.. heard other people complaining about same thing, as this was the answer to get it fixed

No vss harness was added. I still have onstar capability.

    • This is NOT impact damage nor neglect. There were previous class action lawsuits because of such paint preparation st GM manufacturing plant. Not just the Cherry Red Color. This paint is applied in three processes to obtain the desired color.  The manufacturer will cover for 36 months or 36k miles only. That rust is actually corrosion because of the paint process failure. Corrosion is covered for 100,100 miles or a certain months. However their corrosion doesn't include this type. Go figure. Clearly manufacturer knew from previous paint issues. This started 3 weeks ago out of the blue.  
    • Is it time to put a piece of tape over the CEL? 
    • consider doing electrical testing?  I would guess some power or ground wire/connection has a problem.   alldata.com has wiring diagrams, connector pinouts and diagnostic procedures you can use to find where the problem is.
    • can you tell if the reader is actually trying to get codes, and the pcm is reporting none, or is your reader just silently failing because it's not communicating with the pcm?
    • Any joy with this truck seems to be short-lived.   The CEL for P0172 ("bank 1" too rich) is now "intermittent".   I'm not sure where to check, or re-check, and my energy to keep chasing problems with junk is wearing thin. The P0172 seems to set as I'm coming to a stop, completely off the throttle, when fully warm. At least, that's what it's done the 3? times it's set.   Everything appears normal on the scanner EXCEPT long term fuel trim. There's only one bank on this vehicle because it's an OBD 1.5 with only one upstream O2 sensor. At idle, it's around -16.4% and will dip to -18% occasionally at idle or off-throttle. LTFT approaches 0 when throttle is held at 2500rpm. Short term appears normal, much closer to zero all the time. The LTFT tells me the engine is running rich at idle but compensating at higher load. But, why?   The EVAP purge valve doesn't appear to be leaking/sucking fuel vapor continuously. Is it sticking just as I come to a stop and the engine is choking on fuel vapor and sets the P0172? But that doesn't explain the persistently negative LTFT. Disconnecting the purge valve doesn't seem to make any difference.   I suppose that leaves another dang issue with the fuel injector. A leaking fuel pressure regulator, a new leak in the spider, or a leaking fuel injector/poppet valve I didn't see, or a small crack in one of the spider legs.   The vacuum line leading to the fuel pressure regulator doesn't have raw fuel in it. It doesn't even smell like fuel when it's pulled off, not until you suck air through it, then you can tell it leads to a fuel component. I'd consider that normal? Nothing is signaling this is a FPR issue from the outside, at least.   The oil smells like fuel but it's not building volume. I've noticed most oil in most engines smells like fuel to some degree so it's hard to say if the smell is an issue or not. Or if the engine just still smells like fuel because the crankcase was full of it a few hundred miles ago. But it's been changed twice since that original issue of the leaking fuel line dumping fuel into the intake.   Patience is running very thin. Every win seems to be accompanied by two steps backwards, or another issue that leads to removing at least the top half of the intake manifold. Enough! LOL
