I have a N1 running 70 DVD's. Currently I have Sirius SIR-PNR2 on EXT-1, and GEX-P10HD (HD Tuner) on EXT-2, I tried to add CD-UB100 USB PORTABLE MEDIA ADAPTER... If I take out the Sirius or HD Tuners I can get the USB to show up as EXT... But cannot get all three to show up. Is there such thing as a EXT-3??

 

My question is can there only be EXT-1 & EXT-2? Is this the end of the chain? Can there be a EXT-3?

 

Anyone have more than two devices running through EXT on a N1?
