Is Torque Pro worth the upgrade? I'm still using the Lite version and been contemplating upgrading to Pro.
Honestly, I can't remember why I upgraded to Pro. Does the lite version allow for plugins? I know I needed a plugin to get some of the Nissan specific codes from when I was driving my Murano. At any rate, if the lite one is working for you then might as well stick to it. I tried other apps too, but Torque, with all it's quirks, and it is quirky, seems to be the best.
Speaking of plugins, I haven't found one for the CX-9. I believe there is one plugin for a specific Mazda vehicle, probably the 3, but can't remember now. I hope that changes.
