2004 Toyota 4Runner
Crutchfield Customer Review (What's this?)
This went in with 0 issues! There was no drama, no futzing around trying to find something not working properly. I took my time to make sure the wiring connections were correct. I did the firmware update before installing anything. (Always update firmware first on modern electronics!) I putzed with the potentiometer to get the gain set so there was no over-driving (distortion) for a few minutes. The biggest issue was positioning it in the dash where it was out of the way and still left plenty of wiring harness to easily connect the radio & that was not that hard.
Pros: Easy to use. Worked perfectly on the first try.
