I am looking at getting an aftermarket head unit for my newly acquired '03 SLE. Looking for recommendations as the chinese POS that is in my Yukon does not fully function as advertised it was supposed to allow 3G connectivity but its worthless if you can;t get it activeated through a cell provider..... I want to add bluetooth, NAV and maybe XM (but I can stream that from the phone if needed.)

I want it to look kinda factory-ish....
