Not sure if my post got through. Try having a direct inline FM
modulator installed in the vehical by Circuit City or do it yourself.
It installs directly inline to the radio antenna cable, and produces a
stronger signal like you'd need. I haven't tried this yet, but am
tempted. I also live in the Chicago area. Radio here blows, but I
love my XM. EMAIL me if you'd like. n9vu at yahoo dot com. Thanks,
