I decided to go for this based on cost alone, I don't have an ipod but having read some of the other info on the net it suggested that this will work with other Bluetooth equipment.
I have paired up the base with my N95, LG Viewty, and two other Nokia phones, they paired up using (1111) OK and connected but no sound comes out of the unit. This will not pair up with phones that I have tried.
It will also not pair up with Windows XP without specialist drivers as A2DP is not supported in XP, I tried specialist drivers by Bluesoler which connected to the Tunestage and shown that data was being transmitted but no audio was played by the unit. The good news is that with Vista it paired up and work perfectly.
It's a shame that Belkin didn't do a better implementation of the receiver as this could have hit a much larger market than just the ipod, I think they missed an oportunity here!
All in all it shows some promise if you have a Vista PC and Bluetooth and don't want wires. Don't get it if you want to pair it with a phone, the phones will pair and connect but you will get no audio.
There is also a version 2 of the Tunestage, that may be better at pairing to phones but I doubt it.
Hope this helps.
