when my old forerunner 301 stop sense heartbeat and I check to make sure it be not the chest strap , I purchase a new one . love the unit . on my first ride it fall off the handlebar mount -lrb- after I check it twice -rrb- and be run over . no problem , just go to Garmin customer support , explain in a email what have happen and ask what they policy be . HA ! fill in all the REQUIRED information , press send and -- form go blank in both Safari and Firefox . I 'll call tomorrow but if they website , and other review be any indication , I be in for a rocky time . wonder if any Garmin folk actually check to see if they website work . Ok , about two week have pass . Got on the phone with Garmin customer support . very pleasant young man take my information and credit card datum and give I direction on how to return my unit . Cut I a deal for a replacement . get the replacement yesterday and charge it up . must be refurbish because it will not acquire a gp signal to save itself . back on to customer service tomorrow . like I say , great unit , if it work ...
