I like the DashDaq..IDEA....for the GPS ability, even though its not ready yet, Iwant that part of it as I have to have a GPS in my truck for my work....finding people houses to go do my estimates is MUCH easier with the GPS....however..with that said...I currently have a GPS so I am not PINNED down to anything at the moment....I just want more power than my 135hp I have now.
