ok so im finishing my installation of my sound system and when we connected the battery back the radio did not want to turn on......if you turn on the car the nav screen starts up and the warning screen also comes up but after a couple of seconds it will just turn black and that it

If anybody has any comments please let me know ....thanks

 

a fuse maybe?

 

i checked and its good

 

its def. a fuse.

go back over your install.

 

pull fuse #7 for one minute, put it back in and turn on your radio

 

let me check...
