...but I do want a GPS that I can use now and, more importantly later in the year when I set out on my big adventure. So, I'd appreciate some advice. I want. * Upgradable memory (SD or micro-SD card) * .mp3 capability * 3.5mm socket so that I can use earphones to listen to music/instructions * It would be good if it WAS waterproof, although that's not essential as I'll probably keep it in the top of my tank bag most of the time. Those are my major concerns; I'm happy to take suggestions about other issues that should be important using the GPS in a motorcycle scenario. So, what do people reckon? What should I buy and is there a unit that will do the job but not cost me an arm and a leg?
