HUDWAY Cast vs HUDWAY Drive

UPD: We no longer support HUDWAY Cast. At the moment we only produce and update the HUDWAY Drive heads-up display.

There are 3 important functional differences between HUDWAY Drive and HUDWAY Cast.

HUDWAY Cast (left) & HUDWAY Drive (right)

Connection type
Both HUDWAY Cast and HUDWAY Drive can mirror the screen of a smartphone and so basically, act as a second screen. However, HUDWAY Drive has a built-in Bluetooth chip that allows to quickly fetch necessary data from a smartphone and visualized it to HUD. This type of connection (Bluetooth Low Energy connection) has its great advantages:

• phone screen can be locked while transmitting the data to HUD
• device automatically reconnects to the phone when you get back in the car
• your phone can simultaneously be paired to any other Bluetooth device (headset, voice assistant button, car speakers, CarPlay, smart watch, etc).

Video input 
Compared to HUDWAY Cast, HUDWAY Drive lost the ability to wired connect to a vehicle OBD-II port and a smartphone. Also, there are no speakers in it. In return for it, HUDWAY Drive got a video input port (CVBS) which is used to connect external cameras to the device.

Software
By default, HUDWAY Drive app uses navigation and routes provided by MapBox. HUDWAY Cast app is based on OSM (OpenStreetMap) with additional information from other sources.
