Is this compatible with a pioneer avh-x490dab and are all the relevant connecting leads supplied?

Most likely yes, you just need the correct leads to connect it. Be careful who you buy these from though as some sellers like marcomeggio82 are not honest about the taxes which should be included in the price you pay. They may insist that you pay 20% more tax to HMRC if you are n the UK when your item is stuck at customs or with the courier. Took me over a month to get my money refunded from Amazon because the guy was so rude and unhelpful. Personally I'd never buy from a marketplace seller ever again. I also dislike liars intensely.

Is it ok to mount it vertical or does it have to be flat in the ground?

Yes, fine to mount it vertically, the heat sink is the cover, always allow air to be able to circulate in any position
