I tried to search for uXM but apparently it is too short to search for. I just noticed it on the installer this morning and put it on my phone. It didn't work at first (wouldn't allow me to log in) until I found out that it does not use your standard XM radio login information, you have to create an online listener account and that is the login information you use. It works relatively well over Edge as long as you have a strong signal in your area and I am happy I now have radio whenever I go to boring meetings or doctors appointments. If you have an XM radio account, check it out.
