There are two versions of the M324 series:

1. Model M324G has a built in GPS receiver
2. Model M324 (no G at the end) does not come with a built in GPS receiver

The difference between the two models is around $50, but having a GPS function in a VHF radio is a huge plus, therefore we suggest you get the M324G – with the GPS.

This fixed mount radio also comes in two color options: Black version and Super White version.
