Ok, I'll update for those interested, I've bought 3 radios to far since Xmas, I've tried a Zenec nc 2010, returned it as the fakra socket was snapped, & two Erisin units, first was lost in post, second lasted 1 day.
So this search for a new radio constantly made me look at the Dynavin N6, the Dnx 521/5 dab & the blaupunkt philedelphia.
This one I bought came up installed & then removed, still have original receipt & still in warranty so I figured it was worth a punt.
So far I've used the car twice since its been installed it has parrot BT & I've installed the mic just above the steering wheel, very easy to run the cable (built in mic too)
Phone syncs straight away & calls are clear & good quality, not something I found with the erisin. Sat nav is the standard Igo software, not tested that yet but it looks good & is pretty quick.
I'll use it a lot more this weekend & can check out more of the units features & list my findings on here, but so far I'm very impressed.
