I just installed my 8100. So far its a solid unit and it does have some glitches from what I can tell. But overall I am happy. I am still on the 1.01 firmware on the unit. I did some searching on here before I posted this but really never got a clear answer. Some persons where wanting to go back to the 1.03 vs the 1.05. My S5 seems to be doing alright with android auto but the mirror link is super slow and really not usable. But I didn't buy the unit for mirror link anyway. So Im just trying to get someones opinion on it before I do a firmware update. Thanks
