To make my question more specific, has anyone installed a single din (standard size) aftermarket stereo in their 07 Tundra. I have seen the numerous articles about upgrading to better Nav/ DVD playing units (I am not that hi-tech yet) but havent seen anyone post of just installing a better stereo in their Tundra. I am thinking about doing it simply because now that I have the amp and better speakers I truly think the head unit quality is poor and that their arent enough sound adjustments available (treble, bass) to get the best sound available. I'd be interested in some pics of what it looks like with just a single din in the big dash space of the current 6 dics non-JBL system.
