hi guys i have a ls430 with the mark levinson radio/cd it packed up bought another off ebay and this is causing a battery drain i put a new battery on alternator is fine but this seems to be a common fault with the 430 its a 2001 ever since i put the radio/cd which works perfect apart that it drains the battery with the old u/s radio in the car it does not drain the battery any ideas guys really cheesed off as i paid £160 for the radio on ebay this radio is turning in to an epic cheers geno
