That is (in my opinion) a great head unit for the $$. I just put one in my friend's Honda. I think it was around $195 for the unit and I did not charge for the install.
Installing a head-unit is actually pretty simple. Follow the instructions and yotatech and you should have no problems.
If I remember right, you just need to remove a few screws around the dash trim and it pops right off. After that, remove the bolts holding the exisiting unit in place and remove the wiring clips in the back. Make sure you have a wiring harness, as this makes installation a breeze.
