Hello,
I notice you can take off the back cover and replace the battery yourself, even though you're told in the instructions you can't. I cannot afford to replace electronics every 2 years when the battery life ceases to be very good and I'm wondering what model of battery the unit uses? Where can I buy one? If I can replace the battery every 2 years, that would be great. I asked garmin and they said they will replace it free of charge in warranty. I guess no manufacturer plans for the customer to own anything longer than a year, haha.
