My husband found a Garmin Edge 305 at one of the local mountain bike trails, obviously it had bounced of the bike as part of the mount was still attached. We attempted to find its rightful owner with no luck and do not have a need for the item.

The computer sells for about $230 new, this one looks to be in great shape. You would need to buy a mount (about $15) and possibly a charger. My car one is able to charge on my older Blackberry charger so you may have a USB that fits it, also already have USB cables at my house that fit my own Garmin so you don't need a Garmin one necessarily.

$100 shipped, prefer Paypal.
