06' Nav radio...what disc?

[HighSierra86]

Ok so I need some help here...I purchased a brand new TNR radio from the dealer that they had as a take-out. This is a non-lux unit part no. 15229287

What I am looking for is what map discs are compatable with this unit installed in my 06' silverado? I was told to contact the gmnavdisc.com call center but they we absolutely clueless. There are so many discs on ebay I dont know what is the right one. I was looking to get either the newest revision or one close to it for the entire US. Anyone offer any tips or have one for sale?

Thanks
