Right, then make it easily replaced, like oil, if it only has a known lifetime. Don't make someone buy an entire new touchscreen and electronics. Just a combination of poor product selection for the flash modules and poor coding to constantly write logs to that store. This is one reason I don't like high tech integrated into my autos. The tech quickly becomes dated and is impossible to repair or upgrade. Autos (at least honda and toyota) should easily have a 20 year lifecycle if well maintained and 15 if even half ass taken care of. I certainly expect the electronics to last that long, if you cannot do that let your customer know up front and make replacements easy and cheap.
