An ELM327 device should work for any OBDII vehicle found on the road here in the US. They are very universal.
You'll need to ensure you are getting the right reader for your monitoring device though. There are specific ones for iOS and Android devices. The Bluetooth ones will not work with Apple products. You need one which works on WiFi. The ELM327 devices I've see usually state what they work with, so ensure you check. Whenever you get your device, don't leave it plugged in, as the ones I've seen are "always on" even with the vehicle shut off. So it will drain your battery over time. Also, Torque Lite is a free app which works well on Android devices (not sure what's good for iOS).
