Magnus,
Thank you for your reply. I recieved this message from Griffin Technology today, and although I realise they may well just be covering their asses, I just wanted to confirm with you that you do infact have the audio extender working (and what sort of range you get if possible) as the unit costs about $40 in the UK. If it does work, maybe Don could update his tech support guys :)

Hello,

The Audio extender is not compatible with the 4150.
