My nuvi 465t, froze and then the screen went blank, unable to figure out how to recover
You need to reset the GPS.Press the reset button , you'll find it on the bottom right of the Nüvi but it doesn't look like a button. It's basically the sticker with all the information on it. It's just enough to push the sticker carefully with something small, not too sharp so it doesn' get destroyed. The Nüvi reboots, the loader loads and proceeds with the software load. Once this is over, shut down the Nüvi and reconnect to the PC. Then, everything works fine.
However this is caused by a full memory, erase as much saved data as you can to free up space, examples are "recently found" items, saved trip or addresses which you don't need anymore.
Let us know if you were looking for something more else please accept the suggestion.
