I have 2 tested and working 2008 Legacy GT stereo's for sale. These are a great upgrade if you have an 05/06 without the Aux-In feature or the SRS WOW sound upgrade.
#1: Very good condition (see first 3 pictures below). It comes with the Clarion XM radio unit and the wiring harness to connect it to the head unit. You would only have to buy an xm antenna which are pretty cheap these days.
$425 paypal'd and shipped. SOLD!!!
#2: Okay condition with scratching around the hvac area and on the source knob (shown in pictures below).
$295 paypal'd and shipped. SOLD!!!
I just installed a 2008 Stereo, like the two above, in my 2005 LGT in combination with the GROM Audio IPD3 and bluetooth module. It was completely plug and play (no leptronix, no soldering, no silent cd, no extra wiring harnesses, etc.) and I now have an Aux-In, a USB powerline to charge my phone (leaves the 12v port free), streaming bluetooth audio for pandora, mp3's, etc from my phone and a hands free bluetooth phone kit for taking calls in the car. In my last Legacy I did the leptronix and it worked pretty well but soldering on the board and having to install a switch in my dash wasn't ideal. This setup is equivalent to my friends 2012 vehicles with bluetooth audio. Here's the link to the GROM info if you want to read more or buy it:
If you have any questions just let me know. I will be up in the mountains the next 3 days as we are finally getting some snow. I will be home Thursday evening to ship Friday if needed.
