Key Features:

  • Compatible with Holley Pro Dash digital dash displays
  • Provides GPS-based speed signal for accurate real-time speed measurement
  • Plug-and-play installation — connects directly to the Pro Dash unit
  • Ideal for race and performance applications where VSS signals may be unavailable or unreliable
  • Compact, low-profile antenna design for easy mounting
  • Supports data logging with GPS-derived speed inputs

The 554-147 GPS Antenna is an essential accessory for racers and performance enthusiasts who want to maximize the capabilities of their Holley Pro Dash display. By delivering reliable GPS speed data, it ensures your dash reads accurately in any application — on the track or on the street.

Grate customer service

I contacted customer service because I was not able to sign on with google to leave a positive review. they did not get back to me within 24 hrs like they say Also pictures show the incorrect product for the description for example a picture of Interlux 2333N has a description for Interlux 333, different product yes some pictures for the Interlux 333 show the correction description I assumed you don't have Interlux 2333N so I ordered from someone else.
