Denso is of no help trust me on this
if you were under warranty i was gonna say run the disk anyways and if it locks go to the dealer act stupid and get a new nav....
idk what to tell you at this point i mean im very experienced with these systems but i dont wanna tell you something that locks up your navigation system...
Hmm, I've heared that the software update supposedly are on the new map DVD:s (from dubious sources I might add).
When I looked at the file structure on my old discs the structure looks like this:
Volume is 464210-6040A
The new disc looks like:
Volume is 464210-6530
I was hoping that the odd files had something to do with the software update...
Yes I've tried the new map DVD and everything looks fine except that I can't enter any adress, select POI:s etc. all menus are selectable but they don't do anything.
Just as the disclaimer on the back of the map-DVD says
"For vehicles built prior to 2007, a service CD update may be required to use the DVD map disc.
If the adress destination entry no longer functions with this map disc, please see your dealership for the service update"
The map DVD loads but the player goes on and on just if it was stuck or something. The arrow doesn't move when driving either. When I switch back to the old map DVD everything works just fine..
to be honest
i would guess its a firmware rewrite
it basically come down to what your willing to do
if you want to use the latest disc you have to do the firmware upgrade
if it erases your drive beyond function your looking at 1k for a new uk unit from schram or 4k from the dealer
if you think its worth the risk i say go for it
if it was me, id probably do it
Anything you say seems logical and after reading about a guy with a 04 or 05 SRX able to read European maps with hs US unit it seems like this might just work, or at least the map will...
If it don't I'm not going to blame you, just the retards at Denso
Out of the blue my '02 STS NAV stopped working with typical symptoms described in some of the threads "Cannot load system software... " The dealer is playing clueless very convincingly, declaring I need to give them $1000.00 for an "exchange" unit.
If I could buy a copy of the disc (GM # 19115256) from someone along with a copy of the instructions I would be VERY APPRECIATIVE! I tried to send a private message through the forum board but it says I can't due to spam problems (guess they have not figured out what 'captcha' is.) Please reply to my email email@example.com. THANKS!
Just a little info update for you all since our dealership is going through an issue with getting this disc (#19115256) for a customer. Before the days of the GM NavDisc Center (GMNDC) dealers could order any disc part number for their customers. Now that the GMNDC is in the picture there are some restrictions concerning the software update discs. First, only dealers can order the software update discs. Second, each dealer can order one of each software disc (as they need them) for free. Each disc after that initial free disc will cost the dealer some money. The dealer is also supposed to provide the GMNDC with a bulletin that provided the part number for the software update disc when placing the order. In theory, a dealer could order a disc for a customer and sell it to them, but GM doesn't really see a reason for a customer to purchase a disc that they will only use once.
So, to sum up the way I understand this, GM doesn't want customers doing software updates to their Nav systems, but that doesn't mean it can't be done.
I have accidently dumped the software in my 2002 Seville Navigation system. Model number is 25755059. I have been looking to buy or borrow a update disc for it. GMNAV Disc says 19115256 is not available and I should use 15943724. I guess they can only sell that to a dealer. Any information as to where I may find one?
