So I bought a Strada, how could I resist I got it for a steal brand new! Well installed it today and I must say it is a great system! The only downside is after the install there is a not so clean gap on the bottom of it and some gap around the sides and top. The finishing ring they include is way to big to fit in there. So I was wondering if anyone else has this unit installed what did you do? any suggestions? would the ring that comes with the double din kit on crutchfield make it look clean?
