GPS Navigation System Options on 2002 Model

[gotloandocs]

It is my understanding that GMC's navigation systems were made available from 2003. Are there any systems out there that anyone recommends for my 02 model??

Here's a stand alone type GPS deal that works great. Software and GPS receiver ( USB hookup ) for $100. You run it back through a laptop. Not exactly a factory look. You would always need the laptop but you could hide it maybe and route video to another LCD, TFT type screen. You could hide the small ( about the size of a book of matches ) GPS receiver almost anywhere.
