Is there a DIN size navigation system with CD changer control that costs less than $1000? The ones I see cost at least $2000 before installtion and don't do anything my $600 Garmin dash top unit doesn't do... with the help of the factory stereo.

I wonder if I can squeeze a Garmin GPS V inside a W140 dash cell phone cubby.
