Reddit reviews Metra 40-SB30 Antenna Adapter for Subaru FM Modulator

I have an 01' but Im pretty sure that this, or something similar, will work and it looks pretty stock, you also need an RCA to 3.5mm adaptor, I got this one
this thing basically bypasses your FM antenna and gives you an aux input, I put mine under the climate control and the input and switch are hidden behind the DIN pocket

it looks like the antenna size might be different in the 06(i cant really tell), but there are adaptors

it's complicated, i did it when i first bought my 16'.

and don't let just any audio installer do it, they'll just hack the shit out of the harness.

you need about $200 in parts besides the headunit to do it properly

shit and it looks like the link to the blog on how to do it is gone :(

basically you need:

dash install kit

wire to keep OEM backup camera

30pin adapter you'll cut it in half and use it for hooking all these various things together

Maestro to retain steering wheel control, there's a cheaper version though with less features

adapter to retain USB

adapter for stock antenna

adapter for radio so you don't have to cut anything


and i'm pretty sure i'm forgetting something else.

most of these things all have to be wired into the 30 pin connector, it was much easier to figure it all out on my workbench and solder it properly then install everything, took me about 2 days to do.
