Hi all, as you know i'm new to the Z and the forum, iv'e sorted out my tire issue so no more slip light coming on however have noticed when i brake heavy the left side speakers cut out (playing cd's only not the radio) also not sure how to get the horn to activate when using the factory security system, any help would be great. Cheers

 

Hold the lock and unlock button on the remote until the lights flash on the car and it should honk.

For the radio just go aftermarket, maybe something with navigation if the car doesn't have it yet.

 

Yip tried that still no honk.
