I just purchased the Dakota 20 along with a few accessories. I read through the user manual on line and reviewed the list of accessories on the Garmin site. I bought a 16GB Micro SD and a Garmin battery charger that connects directly to the unit via USB. Be aware! The unit will not even read the 16GB card. The most that can be accessed and used is a 4GB card - so don't be fooled (like I was) into thinking you can store a load of data on a bigger card. I complained to Garmin - here is the response I got -
"You are correct that the unit can only use 4GB. Unfortunately, I have never heard of anyone getting a larger microSD card to work. Please try using an actual 4GB microSD card."
Also, DON'T buy the charger!. I complained to Garmin that the charger didn't seem to work. Here is the response I got -
"Unfortunately, the Dakota will not charge batteries while they are in the unit, whether it's plugged into your computer or to an A/C adaptor. To charge the batteries, you'll need to use an external rechargeable battery charger." This response was from Rowdy R Product Support Specialist, 2nd Shift outdoor/Fitness Team Garmin International
