Worth a Try as I really really really want one.

Where can I get a Pioneer AVIC-x1r for under £500???? (SRP=£1200)

Don't mind if its stolen long as it works

ebay, theyre usually cheap if you get them from a foreign country

Your having a laugh right? £500 for an X1R that has a retail price of over £2000....

Minimum Your gonna pay is £1000 and then you will need someone to install it for you as you do usually need an extra component. which is a further £100-£200 on its own.
