I tried to install a after market dvd screen and remove the stock radio while removing the stock radio i blown some kinda fuse now the radio has no power also my keyless entry will not work and when i open the car door the alarm goes off. please help.

 

ok now this may sound a little weird butt go look in the manual. Find the fuse box and find what fuse controls the radio. Take it out and replace it. If you cant find the radio fuse look in the fuse box for the only fuse that is blown and replace it.

 

do you think all the other stuff is going to be part of the radio??? ie the keyless entry and the alarm?

 

yes definately. they are all on the same fuse spot. Go outside to your car and find that fuse and replace it i am almost going to garuntee that it will work.
