Does anyone know why the EQ setting reset every time I start up?

 

HD presets are fine, splash screen stays the same, just EQ settings ie, Subwoofer, Bass Boost, Fade/Bal, etc.

 

Thanks!

 

Details:

2007 BMW 335i

PDX Amps (4.100)

You have a wiring problem with the unit. Check the yellow power wire.

Also... how are you exiting out of the EQ menu after your customizations? At least are you using the custom EQ settings?

I too find it odd that it retains all your other settings, but not the EQ....

 

If everything else checks out, I'd try a full reset...

 

Also... are you using any device to retain factory amps..etc?

I suspect it is reseting more then just EQ. Change the AV1 input to something other then iPod and restart your car. If it changes back to iPod your power wire is not connected properly.

Thanks for the help.

 

I had this professionally installed. I guess he didn't know what he was doing...

 

Any ideas where this yellow wire should be hooked to in a BMW 335i?

On the back of the unit.

Thank you for all your advice.

 

I tried this trick: "I suspect it is reseting more then just EQ. Change the AV1 input to something other then iPod and restart your car. If it changes back to iPod your power wire is not connected properly."

 

I set it to video and shut the car off. When I restarted it it went back to ipod.

 

What is wrong and what do I need to fix. I am going to try to do it myself.

 

Thank you.

 

 

Also, if the bypass is done correctly, should I get an error message at every startup, warning that the Parking break is not hooked up properly, or should this message not show up?

 

Thanks

Thats exactly what I thought. Your yellow power wire has a connection issue. Fix that and the problem goes away. Also, if you get a parking brake error that means the bypass is not done correctly. Lastly, if you had this professionally installed, take it back and demand they fix the problem. You might also insist they use a different person then did the initial install.

As said, the yellow wire from the HU should be connected to a point in the car supplying a constant +12 Volts, independant of the ignition switch.... It's currently probably either not connected, or connected to a switched +12...

Wow! Thank you so much. The installer told me I had to send the unit back as defective.

 

I really appreciate your help!

That is pretty strange.... All installers should know what the red/yellow/black wires do....
