According to the Garmin experts in the class I took. Switching power and ground is about the only way to damage a unit with 12 Volts. They also warned us about powering up for the first time on a battery that might die during the initial software loading.

Get the manuals and follow them. They have detailed instructions on powering the units up for the first time.
