Hi Gerd,

product code is a code assigned by Garmin. I think all Garmin products 
get a code. For example nuvi 3760 is "006-B1101-00", City Navigator 
Europe is "006-D2755-xx", where xx is release number.

Product code is placed in bytes 0x30-0x39 of header. It is encoded as a 
string of 6-bit characters, probably computed as: ASCII code - 0x20.
