Hey I just got my first car ever a few days ago and yep it's a Focus. So far I love it and it's all I think about. However I want to add things to it, such as the Alpine 9857 head unit which would integrate my ipod with the car's stereo system and give me room to upgrade for later. I saw on some websites that the unit does not fit, and I'm just curious if anyone could give me a little info about this. I'm sure it probably needs filler and mounting brackets, etc. but I'd like to hear from other people who have done similar replacements already. Thanks.
