The Holley 26-612W is a standalone analog-style GPS speedometer with a white face, sized for a 3-3/8 in. gauge opening and reading 0 to 160 MPH. Because it takes its speed signal from GPS, it installs without a transmission sensor -- the included antenna routes on a 15 ft. cable to a convenient spot in the dash. Dimmable LED backlighting with a red pointer keeps it readable day or night, and a rear spin-lock ring makes mounting simple.
