the button panel maintains the state of the buttons when you stop and start the engine, and is very stable. I doubled up on the power supplies to the panel to make sure it maintains power. You can jump in and out of the panel program to change music, check the weather radar, catch up on email, use map applications, edit your blog, post to facebook, etc and the button app is in the background. You can't close it, only minimize it. It's a mini touchpad PC in your dash. You can open and edit spreadsheets and word docs if you are so inclined. if you start and stop a lot, no worries, it keeps working and does not reboot. The audio and internet connection to your phone comes back after 5 or 10 sec. with no intervention.
It comes with a mini wireless keyboard with touchpad, backlit for nighttime excursions. that way someone can select music while you are driving. When you open the web browser, the home page is epicmarine.com, so you can get reference and troubleshooting information. Who DOES that!! Amazing, almost as cool as Mypillow.
Please send me a PM if you are interested, I will give you my phone number. I will provide tech support for each system sale.
I will also provide a detailed installation and operations manual and stock spare parts and offer software updates. I am going to add an OBD2 display, tower cameras and other features as development time permits.
