Yes, I searched and was overwhelmed by the stereos people are putting in their 4th Gens. I have the JBL/nav system and the nav has died and the radio is going too. I just want a radio that works and is plug & play which probably means another Toyota radio. I don't want navigation, my Garmin is way better so just a radio that fits. Nothing fancy, my hearing sucks and I won't waste money of quality I can't hear. Suggestions?
