This is from past personal experience.

Some auto insurance companys exclude coverage for removable stereo equipment. Yet will pay off gladly if the unit is permenantly installed. (tools are needed or damage must be done to remove the unit) For that reason I typically don't buy removable equipment. (I'll have to check my papers before I install my new car player.) Given that coverage is not garanteed, I'm interested in having a screw installed thru the sled and into the player. That would of course mean using something like an Airport or a Long crossover cable.

Is it possible to accomplish this without totally bad things happening.?
