GREVEN. First of all
You're gonna find a lot of friendly and helpful advice in this forum.
Next. I have no personal experience with Cobra Company but there are a couple on here who have and they have done nothing but sing praises about the quality and customer service. I have never met any of the people on this forum, but from looking at these 2 fellas work and reading almost all of their replies to people needing help. If I had only enough money to buy one update per model and Cobra Company made it? They would get my money.
