Given the general negative vibe about Bose products on this ng I was
wondering if anyone has any experience of living with Bose car audio
products?

I'm about to order an Audi which, for a few hundred quid, can be
upgraded to include a 'Bose Premium' amp/speakers. This also includes
the Bose 'noise reduction' system which, according to the Bose web
site, compensates for ambient/road noise.

I've only had a 5 minute demo of this add-on and, to be honest, I
couldn't really detect much of a real difference between the Audi
'Concert II' stereo system with or without the Bose options. Given
that it's a £400 option, I'm erring toward not specifying it and
sticking with the default stereo

Any opinions?
