If you have backup from this nuvi, you can look in garmindevice.xml for HWID, or if you have gupdate.gcd in backup, you can upload and we will see how can we help you.

Unfortunately, no backup

084401000270.rgn

I renamed 075401000490 to 084401000490, and updater.exe just said "No updates available for your product."

Can you send me a PM with the UnitID of your device? (is should be show by updater.exe).
Oh, you can't probably send PMs as you have to few posts... I'll ask catymag to fix it.

PM Sent

Thanks again guys! Maybe there is hope yet.
