There are three options with the GO
1) Buy a re-radiating antenna as Selwonk says. It adds several extra wires, and some will tell you it's not as good as the proper antenna, but it has the added bonus of working with any other GPS devices you might want to fit, and still lets you remove all evidence of having the GO installed
2) Buy the official antenna. This will cost you a bit more and adds a wire for the antenna, but it leaves you with a TomTom shoe that's effectively hard-wired into the car. That's great until the crooks spot it and put a window through, hoping that you've left the GO in the glove box. Even if you haven't, they'll probably make do with your CD collection. TomTom have been rather moronic in not programming any anti-theft measures (PIN code, remote deactivation etc.) so GO theft is a serious problem.
3) Mount the GO right next to the rear view mirror. This lets the antenna 'see' though the dotted part of the windscreen (the only bit that doesn't have the coating.) It's also the ideal place for the GO from the useability point of view, apart from the fact that it interferes with use of the sun visor.

A further option is to buy a Palm PDA with a bluetooth GPS receiver and run TomTom 5 navigation software on it. It's cheaper, and you can mount the PDA wherever you like and just stick the GPS receiver in the dotted area of the window. To be honest, if you don't want the whole of Europe on one device (as you get on the 700) then this might be a better bet for cars with coated windscreens.
