Garmin part numbers beginning with 010 are used by Garmin to indentify products as "Shipping Level Part Numbers", Catalog or Kit part numbers. 010 type part numbers do not appear on the actual dataplate for almost all Garmin aviation units.

Garmin part numbers beginning with 011 are the actual unit part numbers, meaning the 011 part numbers are on the dataplate and paperwork of the unit. In most cases, related system accessories within the 010 standard kit and 010 catalog p/n with install kit do have individual 011 part numbers, but are ordered with the single 010 part number that designates a complete kit.
