Thank you your information is quite helpful, as far as the budget goes I would like to keep it under $150,00. The reason I want to build an external display is so that I can see the time without having to look down, the Android is mounted almost flat on my top triple clamp, therefore making it nessecary to look down to see it, which is not an issue at a stoplight but obviously hazardous while in motion, would it be possible to write a piece of software that plugs in to copilot and sends a signal to arduino when the "arrived at destination" message appears? I have to build a project for school and I wanted to tie it in somehow with my current project, which is an old race bike
