I bought this on ebay, got it through the post today. Turns out to be much smaller than DIN sized, so at first considered returning it.... then the cogs in my brain started turning..... I have an old broken Alpine head unit... hmmmm..
I took the surround of the headunit, filed it slightly, and hey presto, it fitted over the cup holder perfectly!
The cup holder also has the small compartment above the cup holder drawer. Oh - it is from a Toyota Supra.
What do you think?
