I have a 2010 Honda Fit Sport and an iPhone 7 and was looking for a way to set up an easy audio setup for my daily commute. My fiancée got me a Bluetooth to RF/Aux adaptor that I like (I mainly listen to audiobooks so the quality loss isn't noticeable) but I really don't like having the ugly sux cable just hanging there.

is there a way to connect the aux Cable to the Rear of the head unit, running the cable through the Interior body panels to keep it nice and out of sight? Would doing this require buying any particular adaptors or doing any significant rewriting?

any help would be appreciated!
