02 and factory nav?

[scottcleaver]

Brand new to the sight and I am not even sure if this is the correct category to open this in but I have done a pretty long search and have not noticed a direction to go just yet. Is it possible to have a gm factory nav unit work in a 02 sierra without a lot of changes being made to everything in the dash of my truck? Thanks Scott

no way, no how. The oem nav radios require class II data... only on 03 and newer.
