Scorpion Trike

I have a trike Scorpion, pedal power, and need to know if there is a Tom Tom or available for use over similar Peddle power.
I have been to several places, but their answers did not seem to answer my question. His need for London mainly and Wales later when I'm fit to travel long distances.
Please remember that it is to pedal power does not use the power of the engine, if it makes a difference.
Thank you

Garmin Edge "models specifically for bicycle use, but have more features for intervals training if you do bike racing (heart rate monitor, etc..)

But their "eTrex" handhelds are quite small, and a handlebar mount is available. Built-in card is very basic and detailed maps of the streets of Europe additional cost. The models can use HCx microSD to store map data more and have more autonomy 25 hours (2 AA batteries). I have a eTrex Legend HCx. The eTrex Vista HCx also has electronic compass and altimiter for when you are not moving or moving very slowly. http://www.garmin.com/

Try it here. They are all for bikes:

I'd say the only problem, that's life of the battery. They can obviously be used when you walk around you. You do not want to leave it on the bike or I'ouverture get nicked.

Yes Halfords sell

You can find many on this site. Just type "bike" in the search box and see all the GPS for bikes.
