F960dab mirrorlink with Sony Z2 response lag?

[sinbrad]

Ok guys, I've had a 960dab for a couple of months now and it's an excellent bit of kit. I did have a samsung s4 but decided to update to an xperia z2 as there was too many hoops i had to jump through to get the phone to work with the head unit. Anyway, as soon as I plugged the z2 into the 960 it recognised the phone and within a few seconds it was mirroring. Excellent I thought, however there is a lag of about 1 sometimes 2 seconds before the 960's screen mirrors exactly what the phone screen is doing. I swipe the screen on the 960 and I see the phone reacting straight away but it takes the 960 that little bit longer to mirror the phones final screen. This happens with everything I try? Any ideas?
