AVN-30D and SIR-ECL1

the Eclipse AVN-30D is the dealer version of the AVN-5435 retail (besides a few small details)

one of the details i am looking at is the ability to add Sirius Sat radio. 

from what i saw of the back of the AVN-30D there is no "E-LAN" plug

is there a special adapter that we need to get or "make?"  i have been told that this unit uses Toyota plugs? if thats true would i then need the Toyota Sirius tuner or something  of the like?

any info would be great, need help ASAP the customer is scheduled for this Thursday to have the unit installed (the AVN-30D) and we would like to at-least tell the customer that the necessary parts are on the way

BTW the eclipse site shows that the AVN-30D is Sirius sat ready and that the SIR-ECL1 is the needed tuner...??
