HN7 Navigator - Want more volume?

There are a couple of options to make the audio output of your Navigator louder:

  • Configure and use the FM transmitter function to output the audio to your car audio system - that way the audio output can be as loud as your car stereo can go.

HN7 units supplied started with batch number 0914 do NOT include the FM Transmitter functionality. The batch number is visible within the unit serial number:


This means all units manufactured since September 2014

  • Plug in an extension speaker into the headphone socket on the side of the Navigator. Externsion speakers are commonly sold through dealers who supply CB radios, such as 4WD outlets (ARB, Opposite Lock etc.).
