bluetooth GPS cradle

The tomtom bluetooth carkit I bought did not come with a cradle for the GPS reciever. I was told that it was now discontinued. I've seen one for sale and was thinking of getting it, as it would be far easier and neater to drop the GPS reciever into this rather than have to plug in the 5V power jack from the main Car Kit.

Does anyone know if there was a reason this cradle was discontinued, and what power connections are available in the back of it.

I believe Tomtom have a hard wiring kit being released as a seperate product in the next few months. Probably to make more money and take the costs of the Kits down by providing jsut the necessary parts.
Sorry but I'm unsure of the power connections in the back of the mount.
