Anyone know about 156 head units?

To cut a long story short....

Our 'wagon has the Bose amp / speaker upgrade.

I took the OEM head unit out, put it in the old saloon and sold the car.

Fitted a rather nice Kenwood CD / Radio / Bluetooth phone / iPod
controller in the 'wagon.

Mrs H hates it, as it's very complicated and doesn't pick up Radio 2
very well.

Question is.... are all facelift head units the same? - I keep seeing
mention of 'mid' and 'high' units - but I thought they were all the
same.

(I'm actually bidding on a Blaupunkt OEM 'Travelpilot' at the moment,
though....)
