Thread: GPS ID, MapID, FID, PID, RgnID ,VenID

Yes, Vendor ID/VenID is a total and complete misnomer. It arose back when the understanding of this was less clear. It was syzygy who I think coined it as a possible identification "maybe it's a Vendor ID" or such-like was what he ruminated. Jetmouse used it in the unl code generator and the usage stuck. Whether it's a Subregion or Version ID seems product dependent. However, "A rose by any other name ...."

It is obviously for old BlueChart and City Navigator especially! If you want to see Subregion coverage so you must use VID.

That's right.

It's not the case. This is an unlock Subregion ID (SID) for maps. It works in conjunction with the RID. When creating a map, it allows you to specify smaller sections of the product that may be unlocked in MapSource or BaseCamp rather than unlocking the whole region (ie to divide the region into smaller subregions). In this case, the unlock code will unlock only the maps that belong to that region and subregion pair.
