Double din stereo help !!!

[Antsmart]

Hi,
seems a fairly silly and probably easy question however my girlfriend has just bought me a 7" milion d2229 touch screen stereo. I can fit stereos and know my way around the wires (well I like to assume) but when I hook the stereo up the power light on the stereo switches on but when you press it on the screen doesn't seem to wanna light up or turn on at all?? Is there a simple answer to this ?? If so please ccould someone help??

Have you tried switching the lives around ?

you normally need to run a seperate permeant live maybe take it from some else

Have you looked at the wiring diagram for the new radio ? Sometimes you do have to modify the wiring.
