Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.

Lets try a master reset on the astro first.. Heres how

Turn off the Astro
Press Map, Enter and Power simultaneously
Wait for Astro to power on
Release Power
Wait for the message Do you really want to erase all user data?
Release remaining buttons
Select Yes
Astro 220 or 320 is now reset. Leave the device outside with a clear view of the sky for a minimum of 20 minutes to acquire satellite data.

And if that doesnt fix the issue, then you will need to reinstall the map through basecamp, heres a guide on how to do so.

the unit turns on the reset question came up but then the unit switches off
Expert:  Dustin replied 1 year ago.

Did you select yes when you seen the reset question?

If so, after the unit switched off turn it on again. And then test.. Is the map working now?

Do you still get the same error?

another screen comes up saying is saving all waypoints and tracks into gpx format but the unit turns off itself after 10 seconds the only time it stays on is if I run the diagnostic screen which tells me that the BMap chk is fail

My apologies for the delay in getting back to you.

It sounds like we cant reset the unit.. At the same time, I believe you mentioned that the device cant be detected by your computer.

If your device is less then a year old, then garmin will fix it free of charge.. If its over a year old garmin charges 170$ to repair the Astro 320. http://www8.garmin.com/support/outofwarranty.html
