mdscorp, I have a brand new and a used changer for your 2001 es, They both include all the panels for a first time install. Leave your email or pm me for all the details.
Was there ever a cd changer installed in the car ?
No, it comes without it from factory, the radio has support for CD player and I think it has a connector and probably a wire harness for it, but the glove compartment would need modification to fit the changer, I understand there are cd changer glove compartment conversion kits ?
how much do you want for the changer ?
any other suggestions so i can install it ?
