There are a LOT of people in the computer business that don't know what they are doing. And other than a Windows based PC, I know absolutely nothing about computers. I have never even tried to use a smartphone. I appreciate all the information from everyone, but have no idea what most of it even means. OSM? Never heard of it. I'm the mechanical type, never been into computers. For my trip next week I just got directions from MapQuest, printed them, highlighted the exits I need to take, and will put it in the map pocket on my tankbag. Rather than try and rig something, what I need is just something to hook up like the GPS in my car, and use, no programming necessary, other than imputing the destination. The only difference is I need to be able to hear the directions inside my helmet. It looks like getting what I really need is going to be expensive. There is a huge price difference between car units and motorcycle units. Even car units with MP3 use an FM transmitter to transmit music to a radio, rather than the cord I use to connect my portable MP3 unit to my car stereo.
