Thanks Gus.
I don't want to open up a whole can of worms and start rehashing negatives and realize you can return the product w/in 30 days. My interest was to see if anyone has been using the 510 for 6 months to a year and had no or very few issues. I think mapping would be nice to have but my typical riding dictates that I don't need it nor can I really afford the extra cash (I know it's against "the rules" but family comes first!). I may just continue using my current method of tracking using my wireless computer and phone foregoing the uploads to strava etc.
