[geno]

Hi guys my 2001 Lexus ls430 radio was working fine the Battery went flat now I noticed the radio just ses audio off it won't turn on from the front unit but works ok from the rear of the car on the rear panel powers up fine. But nothing working on the front of the car all its saying is Audio off like you have before you turn the radio on as normal it has a mark levinson system in my 430 have tried disconnecting the Battery I have checked fuses and there ok any ideas guys it's driving me nuts I recently had the air suspension done but I know the radio was working when I picked it up please please help a fellow Lexus Ls430 owner if I know what it was even if it's a big bill to fix atleast it would put me out of my missery thanks guys

hi

it is possible the radio has a code which needs to be entered - have a look in your handbook to see if its written down anywhere.
