    Re: Poor radio reception

    No where in my reading do I find anything that justifies this statement; "antenna grid patterns interfacing with the rear defog grid." A visual inspection of the the glass shows no connection and I can't imagine what would happen to the radio when you turn on the defroster if this was true.

Also the antenna lead connection to the rear glass is tight, so that is most likely not the issue. I was wondering if there is a powered signal booster somewhere along the antenna lead that may have failed and need replacing? Has anyone else experienced anything like this? These stations had no issues a few months ago, so I am assuming something changed with the car. Thanks for your help.

So I redid everything using crimp type wire connectors, and the problem is completely solved. Would have been better to solder everything, but I don't have a soldering iron handy, and the crimp connectors seemed to do the trick. For the life of me, I will never understand how people think twisting wires together, and wrapping them with tape makes a proper electrical connection!! Oh well, at least the problem is solved, and it was a free fix. Thanks everybody for all of your help!
    Dammm, There are "Man Rules" here.
    When something breaks and/or needs fixing and you are a DIY guy. Then, you Now have a 'legitimate excuse' to buy a New tool/toy.

    You Sir, must not be married. But, preparation of these rules are necessary to protect the rest of us.
    Now, go buy an electrical and/or butane soldering tool and be sure to buy some shrink tubing in various sizes.

    Re: Poor radio reception

    I'm having a signal problem as well. 2007 DTS, with XM, Nav, and adaptive cruise. NY State car that ended up in Florida briefly, now lives in Maryland. I think in Florida they applied dark tint. In Maryland it was a no go so I had it removed. Reception has always sucked outside of Pompano Beach where I bought it. Compared to my 2001 DHS (Totalled recently), it's clear there's something wrong. I noticed the little interface on the drivers side rear window, top was hanging down. Is there any way to fix this short of replacing the rear window? There's also a problem with the XM radio. Says to check the XM receiver. I did, it's there. Looks like it is hooked up right.

    Maybe related - Service parking assist. That module looks fine too. Bought an Ebay replacement - same problem One red light and the service message.
