New unit compared to old unit

* 800 x 480 v 480 x 240 res (in other words same res as Discover Pro now)
* More powerful CPU/GPU hardware
* Units have hardware support for Mirrorlink, Android Auto and Apple Carplay
* Units now have USB rather than proprietary Media in connection, devices inc. Apple now supported via proprietary USB cables
* Bluetooth supports simultaneous connection for two phones
* Discover Nav comes with 3 year Carnet subscription; using your mobile phone as a WiFi hotspot you can gain access to connected services such as weather, fuel prices and live traffic
