Mk4 Mark Levinson Audio Defaults To Rear Speakers

[shake]

Hi,

Bagged a ls430 mk4. For some reason whenever I turn the car on, the audio speaker settings fade to the rear speakers (slightly to the right) and bass, mid and treble are at max.

I change it all down to centre but whenever I turn the car off it jumps back again. (If I turn the radio off then back on, it keeps the normal settings)

I've saved the settings (as in memorised it as a user) however this doesn't change anything.

Am I missing something? The manual doesn't seem to cover "presets" and if you can change them,

Thanks

Do the rest of the settings remain like the radio station presets?

Reason I ask is because most systems have a constant 12 volt supply which is used to retain memory settings and an switch accessory supply for full operation, if the constant supply is missing possibly due to a blown fuse this may explain why your settings are lost after turning the radio on and off.

Another possibility is that the systems uses a "Back up battery" which maintains memory settings, if this is exhausted the same problem will happen.

Hi,

Yes, the memory for the radio stations does stay. It's quite strange.

I'll pull some fuses over the weekend.

Thanks
