Hummbaby,
No question about it, the Kenwood unit is "cool", but it's only major downside is cost. In any event, this has clearly not affected the sales of this unit (
http://www.twice.com/index.asp?layou...leid=CA234800).
However, if you'd like to save $2000, the Pioneer unit needs serious examination. Dan Mohabir wrote a very nice review of this unit (
http://www.gpsinformation.net/articles/pioneernav.htm), and about his DIY installation into a Trailblazer. Suffice it to say that installing it in a Trailblazer appears no more difficult to install in a Hummer (i.e. the General hates aftermarket installation, and if they could, they would tie engine management into the radio to prevent aftermarket radios from being compatible
)
I do have the Pioneer unit, but in my Corvette. I likely will buy another for my H2.
