honestly a carputer is awesome. i put mines in around january and i think it the best mod that i have done to any car. you can do so much with it, which makes it even a better deal. i give credit to 00vegas-solara who has a very clean install. i'm still using my factory headunit but with an aux input. i kind of don't want to do any custom mods b/c i bought a coupe with the intention to keep it for short term and then to resell it, but who knows that may change. but back on topic.....go for it!!! check out

oh yeah and about the hot glue part to the dash, hot glue wont work. you will need something stronger. i'm not sure what the temps in your are are like in the summer, but in MD hot glue would def not stick and next thing you know your lcd is laying somewhere. before i used a gooseneck to attach my lcd to, since i could then remove my lcd when i parked the car. kind of like the whole detachable face for head unit idea.
