Satnav for motorcycles

[remal]

after using my Tom Tom 910 in the US in the last few weeks it worked a treat but I don't want to use it on my bike. So I was looking at a bike and car mounted waterproof GPS. I have read people saying about the Tom tom rider for £250 but have not seen it for that price. Links anyone and what other types of waterproof GPS do people recommened. links would help me get more info on what I would like.

My mother was very impressed with my 910 and wanted to get a GPS herself so I talked her into getting a bike/car one she can use in her car and I can use on the bike.

Looking uop to £300 max but would like to pay less than £200 if I can.

recommendations anyone

thanks
