its knockoff tho :/

has only on here ever used anything from that site/company?

Meh... I think stock is better. That AND now there is a way to hook up a carputer to your stock navi... well at least its creator has a proof of concept on youtube... an acura owner actually.
 
Anyway... thinking about putting a stock navi in a 7th gen? Check out my blog on attempting the task.... still in progress - but lots of good info.
