Joining the ranks
 

of dissatisfied Edge 305 users. Original unit went in under warranty because the down button stopped working. Now the replacement won't power up unless I first reset (hold "Mode" then press "Lap").

Just have to see what Garmin says about this . . .

I couldn't take it any more and ordered the 705 today. Just last week, I did the surgery to fix the spontaneous shut off problem. Th fix worked but then I lost control of the "Up" button ..
