Hi

I just purchased my Z2. Is there any tips I should know before installing it into my car?

You should read the stickies in the hacks/mods section

Get all the right vehicle specific parts, pioneer desired accessories, figure out how to properly perform the video while driving bypass and then get started.

Most importantly, get the right harness for your car.

For example, I got this and wired it up to the pioneer harness. When you're don't, it's like an adapter that goes between your Z2 and your car, without having to make any solder/crimps at the car.
