I can add these questions:
Since which firmware version did you get this problem?
Installed maps: preloaded ,added ,in internal memory,in sd.
Have you master resetted from usual menu or did you clear non vol ?
Have you never tried to downgrade to a previous firmware and then reinstall the latest one?

Been a problem since I've been on City Navigator® Europe NT 2012 2012.20

This is taken from an old saved system stat from when the problem first occured!
Software Version 4.30
Audio Version 2.20
Text Version 2.20
GPS Firmware 2.60
Bluetooth Firmware 3.0.35 P55
PMIC Version: 822
TSC Version: 1.16

I have since updated to latest firmware from Garmin but still on City Navigator® Europe NT 2012 2012.30 map as had only one free update & wanted to get it fixed first, only to find the units out of warranty.

I Have from recall on a 16gb external SD the following...
City Navigator Australia And New Zealand NT 2012.30
Great Britain Discoverer v2

*random reboot issue occurs with or without the sd plugged in*

hard resets done the normal way clearing all user data.. however ages ago when the problem remained I deleted everything from device inc hidden files which have since been restored from an old backup.
I have never downgraded to older F/W build.
I'le have the device to hand monday so will be able to give a precise report on the current system stats.
Thanks.
