"X" is the suffix for replacement parts, likely refurbished units. "M" is what you want to pay attention to... and the M is an RNS-D unit, not RNS-E.Mr Blek said:The European model is 4BO 035 192 P but I'm now seeing new models for 2007 ending in MX. Can these be used to retrofit instead of the P versioned units?
Cheers
