Got a new Kenwood from Best Buy and they give away the sirius tuner. You are right it all just plugged in super easy. The big difference is the new unit is 50w and the speakers in the boat sound so much better. The tower speakers always sounded good. I also went for the service plan, which I never do. And best buy will give me a new one if anything goes wrong for 4 years. I even told them I am putting it in a boat. You know I'll be getting a new one before 4 years is up.
And after 25 more hours still no problem with the oil reading.
