For connectors in battery and speaker wires to the Mobo, be sure its not the LIFT UP variety, just work a spudger or driver underneath the wires and gently lift up, do not pull the wires away from the connector as in the older design. If you are not sure which you have, try lifting up first,as if it works it works immediately.
The battery has a shelf life < 5 years, so if it dies and its not replaced, the unit is still usable but cannot be 'walkable'. USB works lose over 2-3 years to make the unit first unreliable then will break, the USB port needs to be resoldered to the Mobo, they did not design any good mechanical support for the port, its held mostly by solder, which is not solder's purpose. The touch screen can crack with sharp objects so be sure to use only your fingers and get a case to protect it. Its easy to replace, but hard to find the part, you have to buy a spares unit on eBay. Finally the 'lifetime' upgrades of maps and firmware increasingly use more CPU and memory than it becomes so slow to be unuseable, even if you skip years between upgrades. So you effectively cannot upgrade for a lifetime even if your unit is electromechanically sound. If you upgrade too much, just restore to factory and do not upgrade map or firmware thereafter.
