Navigational DVD Question

[Fyrcaptain]

Why does Cadillac have like 8 or 9 nav discs (each for a different part of the US) for their nav radios?

 

Why is their latest (for 05) single disc DVD a version 6.0 when the latest GM single disc DVD is v3.0?

 

 

Will the Caddy DVD discs work in a 0099 TNR radio?

 

Thanks

Without know what nav and/or vehicle model those multi-disc Caddy nav discs were for (definitely not for the Escalade), I'd say that (based purely on assumption) back then, those 8 or 9 discs were either pressed to CD or single-layer DVD.

 

The 6.0 DVD you're referring to is for a entirely different nav model (obviously not found in our NBS GM fullsize trucks/SUVs), hence a different rev. Why it's a "6", I have no idea since I've never had a reason to follow the various revisions for that particular nav. I dunno if there was a 1.0 rev for our nav DVDs but if so, I can only assume that it was for late '03 (when the nav option was first available on the late-'03 Denali/Escalade), then 2.0 for '04, and now 3.0 for '05.

Thanks Toneman.

There are always a lot of the Caddy multi disc versions up on ebay

Disc 1 Western States, Disc 2 Central US etc etc etc up to #8 or 9

 

Then I saw a Version 6 Caddy DVD nav disc and just wanted to make sure that the Caddy folks aren't getting something better in the nav software arena that us regular 'ole GM guys!

The caddy cars use a Denso made nav unit, the new ones are DVD based and the older ones where CD based, that is why they needed so many.

 

the NBS trucks and SUV"s use a Delphi made nav unit and they are aslo DVD based.

 

The two different brands and types will not interchange the mapping disc's
