So i've been looking around and finally this weekend i will change my headunit to a Pioneer with Navi. I bought my Corolla a year ago, i have the S plus trim. I looked everywhere to see if there is any video of anybody switching there's but so far i have seen none. Im just curious to how it will look, has anybody switch theirs? If so how has it performed? Also will i be at risk of someone breaking into my car and steal it?
