The Evo I've just bought has a Chinese double DIN in it. It's got sat nav, full bluetooth, iPod connectivity etc, basically everything a £400+ unit has. Anyone know much about them and what they're worth? I have a W502R here that I kept from my ATR which I was going to put back in but if there's nothing seriously wrong with the Chinese units then I may just keep it considering it does have a lot of features. The only issue I'm having is an alternator whine but I think that perhaps the amp isn't grounded properly, I intend on looking into this.
