Wire up as per diagram.
  • -12v for radio connected directly to -ve of 12v battery (not to ground )

  • Fit 15A fuse in DC power Cable, 5A in ignition sense power cable.

  • chose the correct antenna to suit both your vehicle and frequency.
  • don't tighten cable ties, care needs to be taken not to crush the cables.
