On any of those units except the M3, you're going to have to buy a switch
and annunciator (and perhaps a CDI). This will run you $1200 on top of the
GPS. The install will be quite lengthy, as there are many wires that need
to be run between the GPS, switch, annunciator, and CDI.

Why does the M3 not require an annunciator, just out of curiosity?
