Hi! I'm looking for new android car stereo and want to install Seicane car stereo in my 2007 Saturn Relay. How to install it? Is it difficult to install this by myself or to ask the professional to help?

 

 

I know this thread is from last year, but for anyone who is thinking of upgrading their stereo should probably let a professional do this. I attempted to do it myself, but had to get an adapter box that let the OnStar, door chime and steering wheel controls still work, destroyed a Pioneer head unit in the process. Be careful
