  1. Nice review. But will this work in countries outside the US? This locates the position quickly and precisely, what is the estimated time for search? Thanks in advance 🙂

  2. GPS navigator has become important these days……my brother always complains me about it functioning…..

  3. will this work for India? the gps mapping is still, i guess, not perfect and accurate, or at least not enough detailed when it comes to India and especially the remote part of India…

  4. I’m a sucker for GPS and garmin is really unmatched, they have no real competition except for TomTom. I do a lot of cycling and i have a decent bike computer but Garmin makes an excellent GPS-enabled bike computer that looks incredible.

    For me, i’d probably choose that over this one because i cycle, I like the handheld one above though too.
