Hi I'm thinking of getting DVD player type radio for my mk7 to entertain the kids,has anyone replaced their ford radio with one of those 7" touch screen android ones? Find loads on eBay from 150-350 depending what on spec, trouble is I've never heard of the company's so not sure if they're any good, also does anyone know if the standard functions will still work(six point,steering wheel controls etc) any input I'm grateful
