This has been a frustrating challenge for me too. I have a Garmin Nuvi 1390 which doesn't allow me to upload routes to it. When touring, I like to plan out the roads I want to take, and then not have to worry about remembering all the different names of streets. So far have not found an iPhone app that will allow me to do this easily or cheaply either. I'd hate to have to buy a new GPS unit just to have this feature, partly because I'd rather carry one device (the iPhone) than two (iPhone + GPS).
Any iPhone app suggestions? Or should I bite the bullet and upgrade the Garmin? Voice prompts and a big screen are nice, but I don't need their very expensive motorcycle specific unit. I'll put a ziploc baggie over mine, thank you very much.
