My unit as been tested in Australian Forester with the 6 cd changer. Everything is fully functional since the head unit is almost the same as the one of USDM Forester's.

I have to remind everyone that my aux in works only with USDM cars or Australian Forester. Also standard shipping does not allow tracking and it can takes up to two full weeks for the package to arrive. I saw shipping delay as less as 4 days sometimes also. I can provide tracking number, but you will have to pay an extra.

Module description

The price is 100$ CAD shipped within continental US, paid with Paypal. For order within Canada, please see shipping prices when ordering.

So, as a reminder, my unit works in USDM Impreza/WRX/STI 05-06 and USDM, Australian Forester 04+ with the 6 discs changer and  the Legacy 05-06, 2.5GT and 2.5i. For the 2.5i to work without any cd, there is the need to remove a resistor from the radio pcb (check the installation manual for details). The features of the Leptronix aux in are:

- Provides an input to use you mp3, satellite with the OEM radio.
- No silent cd required
- Automatic detection of music (switch automatically to the aux input)
- I have added a little audio gain in the new unit, so you dont have to use the mp3 line out to have enough output.
- Integrated ground loop isolator, so you can recharge your Ipod while listening it in your car.
- There is a remote switch to manually control the aux in. Three modes are availlable, Off/Auto/On.

                                          - Optional 12 foot audio cable (3.5mm headphone stereo connector on both end)
