I was an early adopter of GPS on motorbikes and at the time the only one that was rain proof and had long battery life (bike renters don�t want you messing with the bikes electrics) was the 276C. Yes right hand buttons but became used to this. I want to do another trip or two before I hang up my leathers but have lost the CD City Navigator Europe 2008 � I do have the unlock key. Garmin helpfully say if you have lost the CD tough � they used to be both technical and helpful. I would rather not use OSM , tried this on a trip in Asia and it was tedious and result was a monochrome image. If I buy a second-hand CD City Navigator Europe 2008 would it unlock and work properly?

Thanks for any advice

John
