You can call or email to your local Garmin office and if you have some proof that it was really your F3(cheque, guarantee, etc.) they can block it by serial number, on Garmin Connect services.
Hi, thanks for your reply. Ofcourse I already contact my local Garmin office. I've got proof that it is really mine - receipt, guarantee, box, serial number & etc. From the Garmin office explain to me that it is impossible to track the unit. Is it true? They can block it on Garmin Connect services - that's all???
