98 Ls 400 Audio Settings Problem?

[mitch - p]

hello guys, im new to the forum. over the years ive owned 4 lexus's. 2 pre facelift ls 400's, a soarer t-t , and now a facelift ls 400 with vvti.

i have a problem with my ls 400 gps/radio unit. it works fine, but the audio settings knob does not work. i cannot adjust bass, mid, high, fader or balance. it is stuck to the front speakers only working, and because of the ill functioning knob, i cannot adjust the fader settings. this is irritating me as the sound system is great but only half of it is working ! anybody had this problem before? or know how to fix it?

not sure what model the radio is, its a touchscreeen gps/radio all in one from the factory. i pulled the fuses to try and reset the settings, it diddnt work, i removed the Battery lead, that diddnt work either. a quick fix would be nice :) everything works on the unit ,bar the audio adjustment knob.any help or comments greatly appreciated !

hi

sorry if this sounds too abvious - to toggle between the different setting i.e bass, treble etx you have to you press the knob it self - each time you press it a different setting will be highlighted - then you adjust it by turning the knob clock or anticlockwise depending on where you want the setting

I've used Autosounds on Scotswood Rd Newcastle and they were very obliging and reasonable. Now tell me you live in Berwick!!!

Hello from Finland, I have 98 LS400 and I have same problem. Last winter my audio and menu buttons stopped working. I have a command system too. I cannot even adjust my clock.. I have adjusted audio system via service menu. It would be great to get this problem fixed but I don´t know how...

Recently read about mapleaudio.co.uk ??? for LS audio issues ..... someone said that other car audio repair shops use this company.
