OK - so I got the mount worked out, and I've now got a way to transfer information back and forth between GoogleEarth and the Mio!!!
So far, I've only transferred POI's...don't know if I will be able to make an entire route in GoogleEarth and transfer it but that would be ideal.
Anyway, the basic premise is shown here:
POI’s on my mio c310x : Eat your Vegetables!
To do this requires:
1) Unlocking Mio, which makes it boot to Windows CE desktop (very cool..hmm, wonder what other apps I could install and run on this...)
How to Manually Unlock your Mio
2) Install iGO POI Explorer software found here:
iGo POI Explorer v1.0 beta
3) Create POI's in GoogleEarth, save them as .kmz files somewhere on you PC.
4) Drag .kmz's to iGo Explorer.
5) Sync Igo with Mio
Other notes: You must have Activesync installed on you computer, as well as .net framework. If you're geek enough, this should be easy. The cool thing about Activesync is that it allows you to do a full backup of the Mio should something become corrupted.
