For an external GPS, yes, assuming that battery is not also dead.
Dead battery
No. It does not require very much power. If the battery is not putting out enough power to turn the starter, but is putting out some power it may still work. If the battery is totally dead it will not work.
No, they should still work.

Could be a dead battery. Put your headlights on and go out front and look at them. If they are not on or very dim you may have a dead battery or dirty/loose battery connections.
Put batteries into a radio then press the on button
Can a Dead Battery Be Charged, and Work...Yes, IF the battery is not damaged [both internally as well as externally], AND it is recharged properly.
it should work fine unless you have it unplugged for too long. i have replaced batteries in these cars before and did not have to reset the radio
If the radio has a security code you will have to insert the code for the radio to work.
