The Acura TL’s control layout is good but not great, mainly because of the myriad buttons scattered upon the dash. As busy as this looks, the arrangement is preferable to having the climate and stereo system functions bundled with the navigation system, even if the touch screen does offer good resolution and can be operated with touch, a toggle, or using voice commands. We tried the surround sound with XM and while it sounded good, it lacked the richness, depth, and clarity that we expected. But then, we’re not stereo reviewers, we’re car reviewers, and the large, metal radio knobs are things of beauty.
