Yup, both my empegs have issues (sadly I think my main unit is terminal) so I've been using a Sony Bluetooth headunit for a year now. Having handsfree that 'just works' is great and now the iPod touch does A2DP it makes listening to stuff off it so much easier. I would love to have the empeg back where it belongs, but since every new car I've been looking at has some sort of spiffy TFT touchscreen on the dash, I think it's unlikely.
