I am newbie to carputer. I have been thinking about building Carputer. I want clean/sleath install to make look like factor GPS Screen (replacing factor audio head). However, I am afraid I will mess my car install completely. I have experience at all handling cars audio, electronics, or anything like that. I am quite clueless about car to say the truth.

I do build my own computer though. However, that really doesn't require much special arrangement. I could easily put together new computer in 30min - 1hour. But installing car PC seem like daunting task to me. I am especially afraid I will mess up the Aesthetics on my new car (that I planning to getting hopefully).

Any suggestion or ideas how hard (time consuming) it be to get done? Should buy in dash Navigation/DVD unit and have professional install it?

Thanks in advance.
