I bought the SLK 55 when if first came out and because the selection of phones at the time was not great, I did not get the phone package instaled. Now there is the bluetooth module that hooks into the UHI I am thinking it is time to get a phone installed. Has anyone had the phone "wriring" installed after purchase. If so, how much did you pay (parts/installation)? Any problems with with it? Share your experiences. Thanks..... -Eric
