Well, touch screen is acceptable , similar like 2-3 old resistive touch screen feel.
Audio quality is below par and it is very annoying hearing a distorted song at high volume in 2.1 million car ... Audio is a BIG disappointment. I am not an Audio junky but even for a normal use, I can feel the sound getting distorted once you increase the volume.
Maps are not top notch, comparing it with Google maps and are not very detailed.
The only handy feature is the Rear View Camera.
I've been a fan of stock or factory fitted things but this has disappointed me and I'll not recommend it , unfortunately
