i plan on doing an install on a scion tc. anyone run into any problems with these cars?
Scion TC's have one of the most user-friendly head units as far as OEM goes. The ONLY one just about with factory RCA style preamp outputs and good equalizer adjustability.
As a matter of fact, the only reason we ever have replaced one was for a navigation upgrade. Other than that, just done tons of add-ons with great sounding success.
