Very happy with it - I wanted something that could store most of my music collection, and be easy to use while driving, and this does it perfectly. Out of the four or so Pioneer products which take an SD card, this one wins because the three line display makes it easy to see a list of albums, or see all the song information at a glance. Sound quality is very good (simple 5 band graphic equaliser is great), and it remembers where you were, even if you unplug a USB device, switch off, then plug it back in.
Installation is as per most stereos, the flip out fascia does protrude from the dashboard somewhat, otherwise it would not flip open. The 32GB (max) SD card holds all the music I need, and is tidier than than a USB device - I could find no other product that came close to having this capacity, and most other products had very little information available. Because this is a new product, the manual was not posted on the Pioneer site at the time of buying (it is now), so I rang Pioneer UK - they were very helpful, even with some quite technical questions, and they emailed me a manual immediately. This pretty much swung my decision to buy, as I knew exactly what I would be getting. I recommend having a look at the manual first, as it describes clearly how easy the product is to use, and exactly what the spec. is - e.g. the USB capacity is huge!
I was surprised how good the multi-control wheel was - even on bumpy roads, it is easy to operate, and not too sensitive, with a positive feel.
The only (minor) negative point is that the radio reception is not quite as good as the previous stereo I had, but then the aerial on a MK4 Golf is not that good either - I think with most car aerials it would be fine.
I like the simple, uncluttered layout and ease of use, and heartily recommend it.
