Things I like: wireless andoid auto...huge navigation screen..allsteering wheel and hvac/heated seats work great.
Things I dont like: long delay for the backup camera to kick on from a black screen, and if you wear polarized sunglasses- you can't see the screen at all.
Other note- the cameras images still suck. Not LinksWell's fault at all, was just hoping it would improve...
