Ordered a new unit with Burjauto on Monday & received today.
Change out is rather straight forward, thanks to the advise I found here, regarding the partial removal of the headliner.
Needless to say, but al works well again.
The old unit looks like new, no traces of moisture, corrosion or anything else.
Unit was € 410,- Sending € 72, and import duties € 135,- Which brings the total on € 617,-
Dealer quoted € 1501,- incl VAT.
