Hi, Newbie here.. I have a 2002 GS300. It has the premium sound system which is ok. I had a 2002 ES300 with the Mark Levinson system and the sound was superior. Is there anyway to upgrade to mark levinson? Are the harnesses the same?

 

Harnesses are different. Not worth the upgrade. Just go with aftermarket. The internals of the ML amps leave ALOT to be desired...they pump out so much heat that they're burning themselves out.

Pretty much tells you the state of OEM car audio. Still has a LONG way to go...

How do u upgrade the stereo if you have nav w/ premium? Is this possible?

Thanks

 

I am interested in this also for my 2000 GS, yes aftermarket is better but I want to stay OEM on my stereo, any input thanks, still searching through previous posts to find something. Thanks
