Has anyone done anything with automating maintenance reminders for the car? I'd love to have an icon on my touch screen or a TTS or something come up when scheduled maintenance is due. I know it is easy to put a timer based reminder but what about somehow tapping into the odometer or some kind of sensor on the driveshaft or something? Something that can determine mileage and send that info wirelessly to a pc or M1 or something? Anyone ever try this? I keep missing oil changes especially in the wifes car because she never tells me the mileage.
