Is the audio system type an ISO connector or a Line In connector? I'm installing the Parrot MKi9100 into my 2005 Prius (non nav/sat). Will I need an adapter kit like this: http://www.amazon.com/exec/obidos/ASIN/B000G70M1Y/ref=nosim/priuschatcom-20? the install manual's page 6 and 7 show the different types... http://www.parrot.com/documents/parrot_dtb_video The main difference is one is sort of plug and play and the other requires wire splicing... Thanks!
