THE standard Celica audio system has an electronic touch-tune AM/FM radio with a single-slot CD player with repeat, random and skip/search functions. ZR adds a cassette player with a six-disc in-dash CD changer. Sturdy construction and special fluid dampening aims to reduce the effect road imperfections have on sound quality. The system has motorised auto-loading and eject and random/repeat/scan functions. Six speakers are positioned around the cabin, including high-mounted tweeters for optimal high-frequency clarity. SX owners can purchase either a three-disc or six-disc in-dash CD changer as an accessory.
