THE Optima's 40-watt, six-speaker sound system includes an AM/FM tuner and a single-CD in-dash player. There are 18 FM channel pre-sets and six AM pre-sets available. The head unit cover also ejects for added security. You will need to study the manual to figure out what the various acronyms mean, as it is quite a complex head unit. Unfortunately, in what is quite a resolved cabin, it is the one installation that doesn't look like it belongs there.
