Now I have a 451 that I installed an Android radio in and initially I had some quirky issues with my Galaxy S5 phone connecting and mirroring. I wiped out all the connection settings and paired them back together after I had all the updates to the head unit. Now it seems to be working fine. Usually it would work fine in the driveway when a person could be all relaxed when they were using it. But when you are driving and need it to work correctly with a minumum of fuss, it seems like that is when it would mess up. DCO
