I have a 2008 Suburban LTZ and some of the fine Detroit residents decided they needed my factory navigation more than me and stole it (Bose, nav, XM, DVD, backup camera, AM/FM and supports RSE). I am installing a replacement tomorrow, but this new unit is an upgrade from my previous model and offers and IPOD AUX input jack on the back of the head unit. Does anyone know if GM sells the IPOD hookup wire for this direct connection? The AUX jack is mini-USB and I do not see any option direct from Apple. Anyone have any insight?
