I have sent an e-mail to Alpine UK to find out if PDX series accepts diff. balanced input. I bought the amp purely after reading your sticky post (many thanks and it is very helpful to all others).
However I had serious issues with the amp and finally I had a response from Alpine UK.
Hi, the pdx only takes a single ended line level input, you will need a convertor to use it with the BMW system....

I will be disposing my Alpine amp soon, but you may wish to update
your sticky thread with a link to this.
Alpine PDX can be used with MS-8, bit ten / one as they convert the signals to sigle ended.
Also my finding are similar for Audison amps (unless stated on their packaging) and they do not accept differential balanced input.
