I'm trying to revive a Denso Bose Nav system for my Seville (factory OE). I bought it used and the battery that keeps software memory in the unit has obvious gone flat. It's bricked. Only thing it will do is accept/eject discs.

A software CD came out in 2006 to fix units that were (already!) showing only a blank screen. GM said to update the AVN system software using an update disc, P/N 19115256.

I have been sent the kwi file that was on that disc and burned it to a CD-R and tried loading it into the Nav. It doesn't work; a screen comes up saying it doesn't recognise the disc.

Has anyone had any luck with loading software on these Nav systems? I believe it's the same unit in the DeVIlle.

I was very lucky to have someone email me the LOADING.KWI file. I burnt it to a CD-RW and it worked.

I know that most folks won't care about the original Denso Nav Radio, but if you have an original Seville/DeVIlle and want to keep it that way the Nav Radio's weakness is that if ever the car's battery is disconnected for long enough, there's the risk that the radio's back-up battery will discharge (these batteries are now about 15 year-old, so even more prone to failure now).

If the Nav radio's  battery fails, the radio loses its software and then you don't have a working radio/CD/Nav anymore. It's bricked.

It's funny how up to maybe 3-4 years ago there were so many threads about this. People were begging for copies of the software to get their radios to work again. I posted this info on the 'other' Cadillac form, offering to make the software file a sticky, and nobody was interested! Everyone must have aftermarket radios now instead of the Nav radio.

@rhdsts can you please send me the LOADING.KWI file please send it to Jhabcdefg79@gmail.com thanks in advance!

You might send him a PM, he might get a notice on his email given how old his message is, I tagged him, I don't think your tag of him was active.  @rhdsts  @James Hetfield

I don't think anyone has the disc. Pretty rare. You may want to check with a Delco radio and speedometer repair facility. 

 

I did look around the GM service info and did find a bulletin (looked up 2003 Deville).
