I also have two other Toyotas including a 1968 Corona
I have a few questions I'm after help with please
The sound system in my car has several faults: The LCD display has some faulty pixels (common I hear). The LCD panel has no backlight. The switches do not light up either (AC panel above is fine). Right-hand channel has no output
Are these problems all likely to stem from the main dash unit? What are my options / sources for replacement?
New Ride - Corona behind

Other electrical faults include:
Seat memory not working (they move though)
Front seat heaters not working (rears work)
Any input / experience very much appreciated thanks
