My radio goes off and on it seems when the car is warmed up the stereo works will changing it fix it?

 

Hi sorry this has probably been answered already but I am trying to install a double din Unit in my m35 Stagea series 2 2005. I have a metra kit 957605 but it's not the aluminium finish. Struggling to find one. Any ideas?
Also this kit doesn't have a pouch to replace the old screen, anybody know where to get one?
Or anybody know how to get my screen not to talk to me in Japanese anymore ( imported model obviously)? And English button control panel for below the screen?
