Additional note: Inside my device on motherboard there is mark "Garmin 105-01996-10 ver.4".

There is another mark inside system file:

-<Model>

<PartNumber>006-B1562-00</PartNumber>

<SoftwareVersion>Software Version 7.80</SoftwareVersion>

<Description>Alpha 100 EMEA/APAC</Description>

<PCB>Alpha X V3 </PCB>

</Model>

Does it meen anything?
