Your dealer should be able to fix it without you having to leave it at the dealer overnight unless it is not a setting problem. But it is a Lexus and you should get treated very well while they are fixing it.Didn't have the DVD/Levinson package in my 06 IS 350. Really didn't want it in my IS "F" but really didn't have a choice. But I don't think it's working properly.
When the Audio system is on, CD or Radio, the center in dash speaker puts out 99% of the Sound. No matter how I adjust it, even full rear, all right or all left, the front center is lounder then any other speaker. In fact to hear any of the door speakers you must put your ear right up against them...
Any hints or clues besides taking the car back in and leaving it there ???
Thanks in advance for you valued assistence.....
You can also 800-331-4331 (I think?) and they should also be able to fix it for you, unless there is a bigger issue with the stereo.
Call or take it too your dealer tomorrow and if they are unable to resolve the issue call the Lexus customer service.
Even though you did not want the mark levinson, it still should be working correctly. And peace of mind is there isn't a better system in a car from the factory than the Mark Levinson.
