    Default Compass Reset?

    Hello,

    I have a 93 MKVIII, I noticed that when I replaced the factory radio the compass eventually stops working.

    Is there any way to get in back?

    Thank U.

    Do you have a subwoofer in the trunk?

    When you disconnect the battery, I believe you need to re-calibrate the compass. Look in your owners manual, it will tell you to drive in circles to get it to recognize North again.

    Sub-Woofer = Why YES! I do! (^_^)

    Driving in circles... Yes, I did.

    Mind you that I replaced the OEM sterio with an after market. (what a sweet @$& unit)

    In the '93s the compass unit is in the rear shelf area and the magnetic field from a large subwoofer can cause issues with the compass.

    You can try repositioning the subwoofer.

    In my '93 I have a simple closed single 12" sub enclosure. If I turn it around and/or position it in the trunk off center it causes no issue. Now if you have a dual 10" ported box like in my '96 - you're out of luck.

    YES! I got it to work again!

    Factory Amp's gone so I didn't need the tray back there anyway.
    So I simply remounted the compass away from the vent holes of my Bass box.
    Vioulla! The compass returns.

    Thanks again you all.
