NAVMAN 4431 Fish Finder (needs cables) in DRIVER, Northern Territory for sale

I have a new Navaman 4431 Fish Finder that consists of the head unit only and a bracket. It is missing the extension cables, although I imagine these can still be purchased seperately. The unit has never been used and has been sitting in a shed for the past 5 years. This finder has the following features.
4.3" screen with a 160 x 120 pixel (Black/white display)
Simple menu driven interface
Water temperature (0.0 to 37.7° / 32.0 to 99.9°F)

Speed and Log information available
150 watts RMS power providing depth reading to 600ft (180m)
20 soundings per second will give good target details
Sonar, A-Scope and fully variable Zoom display
Auto Range, Auto Gain and Bottom Lock
Snooze mode providing depth information at variable timed intervals to save power
Useful alarms including Low Battery, Too Shallow, Too Deep, Water
I have an electronic copy of the instructions available.
Thanks
