I am thinking of going this route instead of slapping in an aftermarket NAV system. I am upgrading my system and I don't really care about a NAV but that is the only thing I like the look of in place of the factory deck. So I figure if this works like the Crutchfield customer service says "basically its the same as changing out your deck" then why go through the hassle when this has all the features I want in an aftermarket deck. All I really want is the functionality, aka pre-outs, etc.
Also you can always get an 6.5 or 6.1 (can't remember) LCD display for it later on if it does become difficult to use.

Not sure if I am supposed to post links like that, but I don't know how else to do it...so can a moderator fix it if necessary? Thanks.
Anyways...if anyone has used it before or something what did you think?
