I wanted to put this post out to let any EOS owners know there is a solution for installing a blue tooth handsfree kit that is much less expensive than a dealer installed option. I added this feature to my EOS and it has worked flawlessly, and it allows you to use the phone button on the steering wheel. The solution uses a Parrot blue tooth adapter, and a special wiring harness from Parrot Kits. (http://www.parrotkits.com/)
If you see this post, and are interested in how I installed it, please let me know.
To date this is the only mod I have made to my EOS.
