I found a way to use the wireless feature without any hacking.
I mounted the transmitter on the fork.
I did not mount the computer on my handlebars, which would have been indeed too far, but used the wristband velcro strap to mount it to the bottom of my handlebar riser stem just above the headset, which put it in range, and also puts it in a more sheltered location, more aero and aimed straight at my view.

I do like all the features, esp the PC link, which allowes me to keep a very good log of all my rides.
