I'm new to this site but i've already found lots of helpful info. I'm thinking about installing a gps/carputer in my 2004 mazda 6 like this: http://www.youtube.com/watch?v=k0qAhdfxInA but I'm not sure if a custom carputer is as accurate and fast as a store bought gps modded to fit in the same place.
any help will be greatly appreciated.
