ok so after getting this installed my initial review is "not to bad". one thing im a little irritated about is i dont see a interface for playing music straight from my galaxy s3. only thing i can figure is i have to add music to the sd card and hopefully play using the dvd setting, according to the manual. not sure why they would specifically cater to ipod only but thats the way it is. if anyone else has a similar nav system they had issues with please chime in. im hoping theres other systems out there that may have a similar setup.
