Mercedes-Benz Canada, according to my local dealer does not support upgrading for 2001 model MB cars in Canada. The PSE Q6820971, which is required, if you want to upgrade, is non-returnable if you purchase it from a local MB dealer - but it does not work - Suggestion: Talk to Keith Valentine at 714-746-5930 - he can sell you an updated version of Q6820971 - and it does work for your bluetooth system upgrade..
