I've got a BMW Z4 (E85) with the professional nav. It's 10 years old and lacking features of the modern TomTom's etc but for simple A to B directions, it's fine. Now, I often use Google Maps to create hooning routes but I'm struggling to follow them. Obviously I can't integrate these into my sat-nav, and I can't copy them over to my iPhone. Fair enough I could make a note of the URL, then open in my iPhone but that relies on being in a location where I can pick up 3G - and even then I can only see the route - and not where I am with turn by turn directions etc. I had something which would be ideal when I went out on my mountain bike - you could find GPX files of routes, it would give you a URL which you'd open up in a GPX viewer app on the phone and download all the data for offline viewing. Then when you're out on the bike, it'd mark your position and you could see where you were heading along the route. Something like this would be perfect however I can't seem to find any sites that will allow you to turn a Google Maps URL into a GPX file. I know you can use the map maker feature but it's SO much more complicated than just typing in destinations and tweaking the route to suit. At the moment I'm having to print off directions which inevitably end up flying all over the car or I keep having to stop and check I'm going the right way. Not ideal! How do other people do it?
