Thanks for this very nicely illustrated guide.

Thanks for the guide. Used it to open up a Nuvi 265 because the battery had been left to discharge below the protection circuit's limit. Connected the battery leads (Green = ground, Red = voltage, Black = temperature) to a 5v USB charger for ~20 seconds to revive the protection circuit, and the unit is now charging again. If you're going to do this, know the risks. Thermal runaways in lithium batteries can be extremely volatile.

Used these instructions to replace battery in my 5-year old Garmin nuvi 205W (which has the same access and internal geometry).

This is great! I have run into a big problem, though. One of the screws is "unthreaded." The head has become smooth, and I can't unscrew it to get the cover off. Is there any way to get it off???
