GPS repeater

[BruceB]

Anybody ever seen something like the 3100 or LMF-200 gauge/repeaters in an pod mounted version that could be mounted on top of the dash?
I don't have room for any more in the dash in my line of sight but would like a gauge/repeater that shows fuel consumption, speed, CTS and maybe course if possible off a NMEA network that would mount on top of the dash.
