Garmin Edge 605 GPS bicycle computer
Garmin's Edge 605 GPS gadget for cyclists is ideal for people who want to both explore new areas without getting lost and monitor and compare cycling performance. You can compete against the device's Virtual Partner feature. And the Edge 605 won't let you be cheated by red lights. An Auto Pause feature stops the timer when you have to slow down or stop, so it won't count against your time.
The Edge 605 has a MicroSD slot, so you can add maps and store additional information, such as data on various rides.
If your lottery win is healthy enough, you can buy optional add-ons, such as MapSource City Navigator software for turn-by-turn directions or a massive-capacity SD card.
