[QUOTE="Firewalker, post: 8791695, member: 676743"] Yeah those Chinese cheap android head units are not known to be very good and have issues like the one you are describing. Quite a few people across a few forums have had this issue, sometimes they can fix it sometimes they can't and they end up dumping them on eBay or locally and buy something from a name brand like Pioneer, Kenwood, Sony, Alpine and what not. Sadly it is just how it is with those units. Very little QC and very cheap components. Couple things you could try is to ground the head unit itself with it's own ground wire to a spot behind the dash and ground the rca's as well just in case. If those don't work might just have to go back to square one and find a different head unit. [/QUOTE]
