I'm running the 7" Digital Dash in stand-alone mode with the GPS module for speed. The GPS speedometer works great, but the odometer won't register any miles; it's stuck on 0.2 miles. When I switch the Configuration to GPS Speed, it defaults back to Dash Speed. I called Holley tech, and he was baffled too, because it defaulted back to Dash Speed on his demo model too. He's going to run the question up the chain, but I wanted to see if any of you had this issue. I've also updated to V5 with no change. Thanks.
