Hi! I have a 1995 Lexus LS400, with the stock "Premium" stereo in it. It sounds great, however I have heard that the Nakamichi stereo sounds way better. So my question is (mind you that I know nothing about this subject) would replacing the radio unit make the difference or would I have to replace all the speakers as well? Replacing the radio is fairly inexpensive and I want an upgrade but I don't want to compromise the look of the car(I think an after market would look silly in my car). If you have any knowledge on this subject please let me know! Also I figure I may as well ask while I'm here, does anyone know about servicing the phone that comes with the car? I've looked all over google and found nothing but I thought I may as well ask, Thanks!
