I know these systems are pretty antiquated by now, but what was the latest disc made for the Nav system in my 2006?

I have two discs. 22846887 and 25847541U and was hoping there might be a newer version that I could source.

 

It looks like TNR V. 2012 / 22846887 is the latest disc for the 2006 model

If you're wanting to keep your truck "stock" that's understandable, I've done the same with one exception, the radio.

The new head literally transformed the Hummer, could never go back, even though I've kept to old one just in case I sell up.

Hope you're keeping your truck.

 

I did the same with my 07 H2. New radio with BT , and an input jack and all the goodies plus gps and don't have to bother with those discs any more.

 

Thanks, it looks like I don't have to buy a disc, I know a new aftermarket radio would be a huge improvement, but I have always liked the OEM looking radios in most of my vehicles. I did ad the Rockford Fosgate H2 subwoofer kit back years ago. It definitely helps with the sound.

OceanB I am keeping my rig, I forgot how much I enjoy it.

 

Great to hear
