I have been searching and came to the conclusion that there is not AUX jack on my 2007. (I think it's a base??? None of our paperwork says???) Am I just blind or do some not have an AUX? (I am asking because I thought it was a given due to my MIL's 2006 base Rio has one.) And if I a right and some Prius' don't have one has anyone added one somehow? (I am a normal, none car-y woman don't laugh at me for asking!!! )
Correct, some very stripped down 07s might not have it. I posted about my former coworker's very stripped down one at http://priuschat.com/forums/gen-ii-prius-main-forum/80578-mfd-version.html#post1126091. https://priuschat.com/forums/knowle...andard-optional-equipment-some-countries.html has a list of the various packages and years. If you have it, it'll be inside the armrest cubby to the right of the extra power outlet there.
Lots people add an aux input to auxless Prius. I am one. There are tons of posts about this on this forum. Unfortunately if you search for "aux" you wont find anything (not sure why). Instead search for DICE and GROM and read some of those posts which will give you leads to many others. Good luck!
