Hey what's up guys. I'm having a little bit of a problem here, you see I bought my STS about 8 months ago and after I bought it I realize the nav disc was missing. About 2 weeks ago I talked GMnavdisc into sending me a free update version 9.0 p/n 22944166. Now before inserting the disc the nav unit says:"please insert a map DVD" and after inserting the map dvd it does nothing but continue to display the same message. Could someone help me with this I'm not sure if I'm just doing something wrong or my nav unit just doesn't work
In addition to what's been mentioned, I'm wondering if you have an old navigation radio in your car. If it was ever replaced with one from eBay or a wrecker, it may not have the required firmware even if it was "unlocked" by a dealer. This message is characteristic of the original firmware.
You NEED the "Firmware Update", and ONLY the dealer can do this,
they need/use an additional disk, and a Tech II tool to do it.
It calls for .7 hours to do this,assuming they have the disk.
Had mine done, paid about $ 66.00 to get it done.
Now I can insert 8.0 Nav disk sucessfully.
Do a NAV Update search, it will explain better.
Happy Motoring :cool2::cool2:
Hmm okay. I would assume that my DVD rom still reads discs considering that I put a music CD inside it and it said "the disc installed is not a map DVD" but I could be wrong.
I thought I read if you had updated every year that one of the discs came with the update. Oh well the update does more than just allow you to use the newer maps.
I remember reading that from one member on here one time. I'm not sure if its really true. It doesn't really make sense that they would have the update come with only one year's disc when otherwise you have to visit the dealer.
Have your dealer check to see if bulletin #05-08-126-001B applies to your car. This relates to the firmware update for some 2005-07 model year STS cars exhibiting the symptom you're describing. It will also provide them with the part number of the update disc set they require to complete the update, if necessary.
I installed a navigation radio out of a 2006 Escalade into my other car and this was the case. One of the map updates I purchased did upgrade the radio firmware. This has only ever occurred one time. My understanding is that it depends on the radio. In that case, it was a Delphi navigation system, not a Denso like those installed in the STS.
It would have been nice if they would have done that with our STSs. I would think you could keep the update on all newer discs (not just one year). If it was already installed then it would just load the map. Oh well, mine are updated.
The storage required by the POI's forced a second disk for a while anyway. It's not like they had excess space. The upgrade also requires use of a Tech II. (Shoulda, woulda, coulda?)
OEM Navigation systems have a ways to go before they beat the aftermarket systems. The advantages they have are screen size & integration with the other systems of the vehicle. I think the winning design model is a universal interface to all carriers' smartphones, leveraging their data plan. ($$$$$$ behind the scenes for manufacturers & telcos fund convenience for us.)
alright guys so I want to the Cadillac dealer and they told me that my nav unit needed to be replaced. so I went on eBay and found this, let me know what you guys think.
Correct. The theftlock used by GM to "prevent radio theft" has the radio communicate with other modules to get the VIN number and then it compares that number to what it has stored internally to determine if it should function.
Oh crap! Are you kidding me? *sigh* so if was to buy that nav unit from ebay how much do you think the dealership would charge to program it to my car?

I'd try a older version map disk before going the full replacement route. As read here many times, most dealers are not aware of the firmware update, and may be assuming since it don't work, it's the unit.
If that's the case that would terribly suck, because I've paid them 130 dollars just to see what's wrong with it. So what version do I need? Version 8.0?
There is another brand new one on ebay where the bid is $299 with one day to go. Not sure if a brand new would have to be untheftlocked, but probably does.
ddalder may know, iwill3rd should know.
Do yourself a favor......the instructions for checking the firmware version of the NAV system are in in this forum. You just need to find them. You long press part of the screen and enter a code.
Also that thread tells what the new and old FW versions are. If you have the old version still, that's probably your issue and you can tell your dealer to pull their heads out.
It does pay to be on good terms with the dealer(s) in your area. They can be a valuable resource.
No, I am not a dealer, work for one, GM, or anyone in the auto business; never have been. I just know that people are more likely to be pleasent and helpful with friendly and honest people. And I don't advise anyone accept less than what they feel is right. It's possible to be insistent and still be nice about it.
If they didn't really do anything for that $130, maybe they would activate a new unit for free or a lot less. It certainly doesn't take them much (as long as you have proof of purchase & ID.)
This is an older thread, you may not receive a response, and could be reviving an old thread. Please consider creating a new thread.
