We're using a Garmin Etrex20 as our bike GPS these days, so our Garmin Edge 605 is for sale. The 605 has been discontinued by Garmin.
The unit is in good working order. The City Navigator card is suspect and sometimes erratic, but we'll throw it in (a $100 item) for no charge.
The unit is priced at $150, firm. Comes with a couple of mounts. Call if interested - 615.890.2502.
