I upgraded the DASH2PRO to the 4.0.30 firmware and to the 4.0.36 that comes with the latest 8.5 software download. Both versions completely stopped the speedo showing anything other than 0mph. I downgraded back to 3.5.x something that it shipped with and speedo works again. I use the VRS signal conditioner to convert the signal from my gearbox sender.
Any ideas what caused the speedo to stop? As far as I could tell the speedo was enabled and configured the same as before.
DASH2PRO speedo stopped working in firmware 4.0.30
