Review on 🚗 X90 GPS Speed Slope Meter: Advanced Features for 12V OBDII Diesel & Gasoline Vehicles by Lance Story

Electronic 8-point compass with north always up, needs to be moved to indicate which direction the nose is pointing. The inclinometer appears to be upside down - is the nose down positive? slope is sensitive. GPS is the best function - speed, location, altitude, time. Note the 1 hour offset. It can be configured, but the instructions aren't the most understandable. it freezes sometimes, a quick power cycle resets it. The voltage display is nice. Plug and wire options - good flexibility. I could buy an analog compass/pitch/tilt if I had to rebuild.
