Look on your disk and see what part number and version number is on it. There are actually several versions that will work in your car. You need to know what your version is now, so that you are SURE of getting a newer version. The most current one out is... Part number:.20857425U is Version 4.1C Retail...try GMNAVDISK.COM Maybe a little cheaper...I would try E-Bay. Link to comment Share on other sites More sharing options...
JACK Posted July 26, 2009 Author Report Share Posted July 26, 2009 It appears to be a copy, all it says is backup disc 07, dts, sts, cts, etc Link to comment Share on other sites More sharing options...
Texas Jim Posted July 27, 2009 Report Share Posted July 27, 2009 It appears to be a copy, all it says is backup disc 07, dts, sts, cts, etc Hmmm...hard to tell what version it is from that. Do you have a digital clock in the upper right corner of your nav screen? The latest version adds the digital clock. Link to comment Share on other sites More sharing options...

Texas Jim Posted July 27, 2009 Report Share Posted July 27, 2009 No digital clock OK. one more question. Did you buy it from a Cadillac dealer and is it CERTIFIED? Sorry ... thats two questions. If the answer to either of these questions is "NO"... Go to https://www.gmnavdisc.com/ and enter your VIN number. The car is entitled to at least one nav disc, maybe two, depending on build date. If the previous owner never redeemed it...you can. They don't care WHO the owner is...the disc are for the CAR. Link to comment Share on other sites More sharing options...

Texas Jim Posted July 27, 2009 Report Share Posted July 27, 2009 Website also says free disc not available, part # for 09 update 25974486-$199.00-but is on back order. Just went to the website. There is no longer any place to enter your VIN number. At least not that I could find. You can call them and see what they have to say. I would probably go to ebay or Craigs list. It would be cheaper and not be on back order. Trust me on this one...I don't care WHAT it says on the NAVDISC website... The newest number is...20857425U. It is Version 4.1C The one listed on the website is Version 4.0 4.1c replaces 4.0 Link to comment Share on other sites More sharing options...
