So... ummm...
You've got a Starcom box on your bike... and the TomTom Rider...
And then you got this Bluetooth thingee hooked up to your Starcom box?
And as the TomTom Rider has got a built in Bluetooth you've now paired the Starcom box with the TomTom Rider...
So you can now hear the TomTom Rider voice prompts etc, through your Starcom thingee..?
... and if you'd have a BT helmet you'd be completely wireLESS (is more).
Did I get it right? What did I win?
