Hi Dennis,
You mentioned that your unit does not power on. Here are some common checks:
Power connections: Please make sure the ACC, BATT (+12V constant), and ground wires are properly connected and have good contact.
Fuse check: Verify that the fuses for both the unit and vehicle circuits are intact and not blown.
Ignition status: Some vehicles require the ignition switch to be in ON or ACC for the unit to receive power.
Voltage check: Use a multimeter to measure the voltage at the unit’s power input; it should be a stable +12V.
We recommend checking these steps first to see if the issue can be resolved.
