Hello all - I'm wondering if anybody has a fix for this. I have a 2003 X-type 3.0 with NavSat integrated ( Denso system). The first issue that I was having was that it suddenly disable the POI - I could not enter any address either. So I wanted to do a system restore to get it back to work. I pressed the phone+menu to get into the diagnostic tool so it lets me restore the system. I accidentally hit the S/W button on the screen menu and then it asked me for a S/W CD- I believe this is the system software to flash the memory. I do not have that CD and it would not go back so after I shut the car down and turn it back on the screen is blank out ( totally black) and all the functions in the panel are not working. Is there a way to get it back up?

Thanks all.

 

there was a email or bulletin.. for this.. but doing this there was a risk of nav reader failure.. will check later

 

have you tried to holding phone.. and menu button? disconnect the battery?

 

Do the hard reset first as Genius said. If you go to software update and shut off the vehicle prior to it finishing, it can fry the nav reader. But I think that is only when you are acutally updating with the disc in it.
Try hard reset, then let us know. You may need the software disc.

 

I did - I hold the phone+menu for more than 5 secs. and nothing. Also, disconnected he battery ad nothing. The AC is set to the from defrost and I cannot get rid of that. Radio is working but the LCd below the nav screen is blinking ext 50 and 51.

 

I dont have the s/w cd i hit the key by mistake and ask for software and didnt come out of there so I shut down the car and that's when all happened. When you are acutally flashing you can damage the flash memory of any system if yu disconnect or power off while it's flashing, but since I wasnt I dont think the memory or anything is damaged. Just that stayed in that state and cant get out of it so I get a blank (black ) screen.

I would start by inserting the software DVD into the reader. Not the map DVD. But the actual software disc. Where are you located? Is your vehicle still under any warranty? PM me the last six of your VIN.

 

Just PMed you the VIN - Nah I dont have that DVD only have the Maps DVD

Thanks for all the help.

 

So SolidX,
Do you have a good understanding of burning DVDs?

 

Yes - Im a programmer - CS in BS and it's not the kind of BS - LOOL

 

PM me your email address. I will send you a file. You need to burn it to DVD-R loose then start car, remove map dvd and insert the one you burned. Screen should say updating. If it doesnt, just let it run for 1o minutes, then cycle ignition. I hope it works. If not you likely need DVD reader.

 

when you say loose you mean just drag and burn or is it an ISO, UIF image?
Thanks.

 

Just drag it in and burn it.

 

Ok kool!

 

THAT WORKED!! It loaded the file and screen came up after 3 minutes ~ Thanks FJTech - YOU ARE DA MAN!!! - so i guess I will keep searching for the S/W update file for the system !! Thanks a million to everyone else that helped! - Found new place to be !

 

Dont keep searching for s/w updates. That was the latest one. What you need is map DVD. I am in process of trying to find the 2008 disc. Will keep all posted.

 

Thanks FJTech for everything- I found a Cadillac DVD for 2006-07 but need 2008 - that one worked but the map is a bit slow.

 

FJTech might be busy responding to my PMs LOL

I got s/w version 8 something ( gotta check for exact number) I dont think it goes higher than that.
