Toyota sat nav

[Major Bloodnok]

I've got a dealer-fitted Toyota sat nav in the MR2. The thing is that I don't use it much and the display's in an awkward position. I'd also like to change the head unit for something better (one that plays MP3 discs, for example). So, my question is: is there any sort of market for selling the sat nav unit (obviously to another Toyota owner) or should I just leave it in place and reconnect it when I put the original head unit back and sell the car?
