hi
i would have a look at how the apb behaves in the ensca track when you visit today.Ben is the only person to post what i had suspected all along,that for anything larger than a normal out the box layout the current becomes an issue again.
It might not be as bad as a standard c7030 was but if you have a pbpro with the sh mod its going to be a backwards step.
IF,ssdc comes out for pbpro and apb gets some sort of power boost they will be equal to each other,apart from the lap display tower of course.
I am unsure as to why this can not be used with apb,is it to do with to many volts in the aux cable?.
