I've been browsing google but can't really find a definitive answer. Some say iSimple, others say USA Spec. Can anyone who has had experience on the matter fill me in about the pros and cons for each? Even though I have a bunch of older ipods as well as a iphone5, I would like to get something compatible with all phones / mp3 players such as a headphone jack as my friends with their galaxy phones are always in my car too. I noticed that the iSimple only comes with the older iphone/ipod connector.

 

have you checked out the FAQ?

Isimple's have multiple input options. I always keep an Itouch connected in the center console and there is a 3.5mm jack to connect to anyone elses device if needed. works great, no complaints

 

anyone know a good spot where i can get a installation setup for my ipod/aux input?
