Hi. I'm thinking of installing a Pioneer AVH-X3500DAB in my Vectra. (Full CAN bus facelift). Has anyone on here fitted one of these? (Or indeed the very similar AVH-X2500BT)

If so I'd like to ask you a few questions.

Firstly, what do you think of it?

Secondly, I know I'll need the steering wheel control interface cable, a panel adaptor and a DAB aerial. What other bits and bobs might I need? Any recommendations on these?

What about the mechanical mounting of it? Is this pretty straightforward with the supplied cage?

Finally, am I correct in assuming I'll lose the ability to switch the BID display between gallons and litres? (the measurement units setting not being accessible from the steering controls).

Sorry to ask so many questions at once but I'm trying to work out whether it's worth buying while it's on offer at Halfrauds.
