Hs Rns Dvd Navigation Problem

[Rafal]

Hi evryone

I have a problem with my navi.

I try to make an update to 5.3 Software so i can use 2013 maps.

After the update finish on the screen it show "Update Succes Restarting Radio"

Radio turn off after 5 sec and don't come back on.

Now its not working at all :(.

Can someone help me ? Any advice ? Where i can find someone to fix it ?

With radio the A/C is not working too so i cant even turn the fan's on.
