Cable hell!

just bought this GPS reciever intending to use it whilst out on my bike - the problem is that it comes with a female PS2 connector and a seperate cable (also pictured above) which comprises of a car charger jack with an XDA 2 connector cable and a male PS2 connector cable comming out of it.

My concern is that because i dont own a car and my XDA 2 had not arrived yet, so does the charger jack have to be plugged into the car in order to use it?

Thanks

Welcome to our forums.
You XDAII will run of its own battery power but that cable is used to provide power for the receiver. Did you mean bicycle or motorbike? If motorbike you could hardwire the cable to the bikes electrical system for power but might look a bit messy.
