Hello everyone! New to the forums here! I recently got my 2nd Mazda, a 2015 Mazda 3 i Sport back in November 2016. Love the car so much. Some things I'm looking to try and do is get the Nav system up and running as I didn't get the chip when I bought the car (used) as well as try and install a reverse camera. So if anyone has any advice, I would greatly appreciate it!
