New additions include a 315-watt Infinity audio system and support for Android Auto and Apple CarPlay.

Hyundai has detailed a modest list of minor enhancements for the 2017 Tucson lineup.Buyers can now select an optional 315-watt Infinity premium audio system, available on the Limited trim levels. The add-on features Clari-Fi 'music restoration' technology, claimed to help compensate for quality lost from digital audio compression.

The Limited edition will receive standard Apple CarPlay and Android Auto support, which is continuing to gradually roll out across the company's lineup..

Lesser Eco and Sport packages will also get a few trickle-down upgrades, including console-mounted rear air conditioning vents. The Sport variant gains new door panels with upgraded materials for a more premium feel, while all cloth interior colors will benefit from stain-resistant fabric.

The changes arrive just one year after the Tucson received a complete overhaul, built upon Hyundai/Kia's latest midsize platform architecture. The company has not adjusted pricing, which starts at $22,700.
