I've used the 522gw with rear cam I have it installed now dont think there is a 255 though the 522 is really good with rear cam aswell nice and easy to install and even had to use the footage once and it was good quality.

I have and using a 522gw now and having used most earlier models does not seem the same quality as others versions so wondering if the A129 would be better
