I've searched around a bit and cannot find answers to these specific questions about the 510 vs 520.
1) Is there a particular reason why Garmin went away from the touch screen 510 and no touch screen on the 520? It seems that touch screen would be better, so I'm wondering why they made the change.
2) I've read that many of the features on the 520 will be available on the 510 thru a software update. Once it's updated, what will be the advantages of the 520 over the 510?
3) Would I be able to transfer profiles and stuff from my 510 over to the 520?
Thanks.
Gary
