i guess everything is personal preference to what is the best system (factory or aftermarket)
the MyGiG loads all the map info into the hard drive so you never even have to load a CD to get a route. also the system automatically replanns your route if you miss a turn or go the wrong way. and ofcorse you can add stops to the trip (like gas stops and such using POI)
and dont for get the real time traffic and sirius radio.
what i love is the ability of the voice commands and the steering wheel controls to work the radio, hard drive, jukebox, CD's and nav
plus i am one that loves the factory look of the unit
the prices of the MyGiG have not gone up from what i know (but i could be wrong)
each and every unit has its good and bad points and its all what the person likes.......its just like wheels and tires everyone has their likes and dislikes, but that doesnt mean one person is right and one is wrong. as long as you (or me) are happy with what you have thats all that counts
