Is there a way to tell from the OEM nav unit, I think it is a Delphi 15204334 that came in some GMs through '06, what the version of the map disc is? I mean besides looking at the disc. I saw a photo online somewhere that seemed to show that radio with version numbers displayed on the screen but I can't find how to do it.

 

This is the screen I'm trying to get to http://www.tahoeyukonforum.com/forum...ad.php?t=38356

I know you can press Seek Up + Nav + Nav RPT to get the HU version info but that is not the map disc info.

Any ideas or is anyone here on that forum and able to ask the poster over there how he did it? I'm not on there and don't want to do a bunch of garbage posts just to be able to send a PM and I'm sure there are enough knowledgeable people here to figure this one out.

THANKS!

 

I just posted over there and asked for a how-to. But that thread is about two months old, so may not be anybody home.

 

Thank you! I'll post if I find out before then.

 

An answer was posted on the other forum, press and hold Nav Rpt + Setup for at least 10 seconds but my radio has Config, not Setup. Tried Nav Rpt + Config, no joy. There must be a way. Still searching...
