I have changed my plans for my Passat, having recently (within the last week) bought the following unit. It is absolutely brilliant and great value, the only thing I don't like is that the Bluetooth quality is nowhere near that of my factory-fitted hard-wired hands free kit (it works fine but, like a lot of Bluetooth kits, sounds a bit faint by comparison).
This is just me being pernickity, but I use my hands-free kit for hours every day and would rather have that working 100% as I want it.
Therefore, if the buyer collects from York, I will let this go for £549 (paid £649 a few days ago) and even include a double antenna adaptor (£29).
It is totally unmarked, and fully working - comes with box, wiring, instructions etc.
