I have a unit like yours and I need a copy of the flash memory to bring it back to life..
Can you please help me with this by making the copy with the utility autorun_armv4.exe (winCE application) that will make a copy of the flash(32MB) on the SD card.
The utility is here:

To update the maps for AA navigator I'm not sure where to get them, but when my unit was working i was using IGO8. The unit has the navigation software on SD so I copied IGO8 on sd and rename the folder the same as the one on sd, also renamed the Igo exe like the original exe. Before I do this I renamed the original navigation program folder or copy on computer to have it just in case.
