Easy installation.
The display is large and clear. The functions are simple and easy to use. Great purchase decision.
Every person was willing to help me when I needed and the whole purchasing process was smooth. [And, E.I.] was recommended by my mechanic.
Love the situational awareness that the CGR-30 Combo gives me. Easy to read and understand displayed information.
Works Great! Love it!
Nice product and good product support!

Good reviews and I don’t have to modify my panel. Additionally, the reps at Oshkosh were extremely helpful and answered all my questions.
