I've had my Garmin Edge 305 for almost a year and it's been working well. However, in the past weeks, I've noticed that it's taking longer and longer for it to find and lock onto the satellites. When I first started using the 305, it would take 30-45 seconds max to lock on. Lately, it's taking up to five minutes to lock.

Anyone else have this issue? I use the 305 about 2-3 times a week for the past 9 months.
