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
