I am just wondering which key on the remote won't work....will the ATT and OPEN (the one opens and closes your headunit face) work??

thanks

 

While I don't have a Sony, I have a Pioneer Premier HU, and I got ATT to work. I have it set for both VOL UP and VOL down at the same time, and it engages/disengages ATT.

 

I have the PAC and a Sony HU but its not hooked up yet. Do you need the Sony remote to pick up the signal for the PAC to work. Thats what some guy that trying to hook it up for me say, but I don't he knows what he is doing.
