Ratings and reviews

Great app. I would give 5 stars if it was possible to connect to multiple modules at the same time. For example, you can not display engine temp and transmission temp on the same display.

It is almost completely useless, it cannot connect every time the car starts. I have tried both options for android auto in the settings without any result.

Put app on its own device mounded in car, that issues solved. Requests, ability to back up dashboards and other settings to sd card or USB, better ability to shape displays including deform guages, a linear guage, And not to go numb when it does not have an internet link. Also please allow hiding nav buttons and allow extending display into cam punch area (this setting in on the dev end) edit; update wastes even more screen. Cant use compact devices in landscape anymore 😞
