I am sure there are some post out there already about this... but this site is really too big and the key words brig up way to many posts to go through them all. SO maybe someone will have some input on this or even a link to a post that totally deals with what I am going to ask. I just got my 2003 Trailblazer and my bose system sounds great but won't play CD's always with the "check cd" error. So i heard that it is hard to switch out the bose system (it cost too much) so I decided maybe I can get the thing cleaned and add the "add an amp" harness as well. I have heard you can add an ipod to the bose system. Now with all that said I have 3 questions.
1. Is the bose system worth cleaning or am I better off spending the little extra money and replacing it?
2. What model and what luck have people had with the "add an amp" harness?
And finally
3. Will I be able to hard wire my ipod to the deck with out using the static involved FM converter to my bose system?
Here is the deck I have.
Thanks for any help you can offer!
