I've acquired an older 32GB iPod Touch 3rd generation (iPod3,1 iOS 5.1.1) to use for music in my car. It's a dedicated device, and will stay in the car, plugged into the USB port so the car's audio system can interface with it. It works well; I can pick songs from the car's UI and play what I want. Also, I can use WiFi, which reaches out to my driveway, to sync new songs onto it from my desk. Awesome! My question, though, is... Will the iPod eventually fail because of the heat of the sun on it? Battery life isn't a concern as it has power all the time, even when the car is off. It's going to be there in the heat every day, though, so I wonder. The unit was extremely cheap so it won't be a huge loss if it dies; I just want to know how likely it is. It's in a well shaded compartment in the car, but... I live in Miami. Hoboy.
