Excellent!!!!!
I bought this product at the recommendation of the guy I spoke with on the phone. Let me tell you it exceeded my expectations by far!!!
Apparently the previous version had some issues with chimes and the battery running down due to the radio not completely turning off. Not this one. I had it installed for 2 days now and battery is still strong as a ox. The chimes still sound the same as before and this product also made hooking up the after market 2din head unit easy. Get this one it is the real deal folks!!!
