Advice needed re. GPS for XDA I

[Batman]

Morning all,
My first post, please be gentle...........

I have an XDA I with TomTom 3 installed. I have been told that I will need a GPS aerial.

Q1. Where can I get one, and
Q2. Will it work on my motorbike?

Thanks in advance,
The Batman

Batman, it will work on your bike as long as you fix up a power supply to the gps. You could fit a cigarette lighter socket.
