Finally managed to get a pic of it while switched on - sadly not a great one as the garage is quite dark and the car is covered up for winter. It makes the display look slightly bluish but in reality it’s white, with the two control rings being blue.
Sound quality is good. No better or worse than the 10 year old Pioneer one it replaced. Main driver for changing it was to have something more subtle, so the black finish (as opposed to the silver of the old one) and the 2 chrome edged control rings fitted much better with the standard interior. I also wanted something that had a usb connection for phone charging and playing music - the Bluetooth and in-built microphone was a bonus, as was finally having a clock - something Mk1 owners usually have to live without!
As an aside, the best improvement to the sound quality came from adding a wind blocker with speakers from a Mk2.5. Because my car has the two-piece seats, the speakers sit right in the gap between the seat back and the headrest giving great sound quality even with the roof down, at speed.
Cheers,
Brad.
