I am thinking of getting a Mygig with navigation, and was wondering if someone can post up the specs and features of it. Also how would the mygig compare with aftermarket head-units of an equivalent nature???? I Have seen some people selling these on eBay, craigslist, and they are a lot lesss then an aftermarket......this is also another reason i am asking!!! Can anyone tell me what all Chrysler/Dodge Vehicles the MyGig came in??? Thankz in advance for everyones help......
