(G) Blaupunkt Travel Pilot Lucca GPS

I’m thinking of getting a Blaupunkt TravelPilot Lucca GPS unit. First of all, has anyone had a chance to try it? Also you can get a Smart Cradle for it, it has a cable that can be connected to the Blaupunkt radio – I guess to the AUX input (the site states that all Blaupunkt radios built after 2001 has this input). This way the unit is charged whilst driving and navigation voice instructions can be received via the car speakers. Now, I wonder if the GP’s AUX input is still free, since the Blue and Me is already connected to the radio? Also, what is the best way to lead this cable to the back of the Radio?

By the way, I hope there will be a simple GPS solution for Blue and Me in the future, as the original Microsoft press release stated.
