Entertainment tech starts with the standard Bose 11-speaker sound system or an optional 13-speaker Bose Centerpoint Surround Sound system and continues with Cadillac's 8-inch, capacitive CUE infotainment system. I'm hoping that Caddy's made improvements since we saw this system in the 2013 ATS. However, the CUE touch screen is not the only display in this sedan's dashboard. The CTS is also available with an optional 12.3-inch LCD instrument cluster that features four, driver-selectable layouts. Drivers who want yet another tiny screen can also opt for the full-color HUD.
