: Navigation DVD version?

09-06-05, 10:47 AM
I still have the 3.0 version of the DVD, but am getting ready to upgrade. What is the latest version ( I have heard 4.0 and 4.1) and when is the next version out? sombody said 5.0 would be out in sep/oct.

Futhermore I have heard the disc contains firmware upgrades and or software as well? is this something that will be installed automatically or something the dealer needs to be involved in?

Version 4.0 was out late last year, hopefully version 5.0 will be out soon. I haven't heard anything about firmware fixes.

It claims version 4.1 and including firmware upgrades.

<<This unit is for both touch screen and non touch screen navigation units in GM SUVs (ie Denali & Escalade)>>

The SRX/XLR Navs are not the same brand unit as the Denali & Escalade's. Ours are Denso, whereas the others are not. Don't know their mgfr, but some have speculated that they are Visteon and/or Delphi.

Any body who can look up the part # 15792651 to see what this really is?
