Hi, I have a Drive 5 with USA maps and there is no lifetime maps assigned so I can't update via Garmin Express or add maps via a micro SD card.

I have unlocked a Garmin unit before but didn't want to brick this one as it is probably a US unit - here is part of the device xml;

<Model>
<PartNumber>006-B2267-00</PartNumber>
<SoftwareVersion>610</SoftwareVersion>
<Description>Drive 5</Description>
</Model>

Can anyone advise what I need to do for this unit.

Thanks in advance.
