Hey guys kinda hating I bought the cdml-100 kit and my s4 and s5 doesn't work with the unit what am I able to do to improve or hack my unit. I can't find anything bout a secret service menu or anything custom. I'm nearly ready to sell it. Please I beg you HU gods help me lol

Anyone

S4 is not compatible with MirrorLink, and even if you can find a phone that is "supposed" to be compatible, the Android version it's been updated to might not.

MirrorLink is a buggy mess and it doesn't work.
