That's worrying. The guy obviously researched enough to know that the required adapter was 12-14V, and enough to find that review but didn't find riocar.org or this forum...That's not easy. Add to that the fact that the stated history is dodgy (how many friends would just give away a UKP1200 player because it's suffering from the #1 reported problem that is easily fixed?), and the absence of a sled, and you've got to wonder what the serial number of this unit is, and whether it has disappeared from someone's car in the past.

Eighty quid though...
