Hi Terry, Yes it's the 4 cylinder version Sportivo, (Assumed that you guessed it because I said the CD was without the casette deck). There seems to be some tweeters or something near the edge of the front panel and window on both sides. So firstly that was why I'd assume it was 6. Btw, thanks for all the replies guys. Still, is the removal procedure the same as the Corolla as shown? The air con/panel beneath the stereo looks sort of different from the Corolla. I've done installations (amatuer) on pre-air bags cars but with these new cars, anyone know if you can accidentally set off the air bags (expensive to put em back in).
