Hi, I'm just starting a worklog for installing the AUX-IN for '03 Xterras w/o the RF stuff.

I just picked up my 8-pin DIN plug from Fry's. http://shop4.outpost.com/product/2421710?site=sr:SEARCH:MAIN_RSLT_PG $.59
and my 6" mini-to-RCA adapter for $1.49.

I already have toggles mounted on the console.

Will post up pics and progess soon!
