I got the MyFi activated. My #4 button does not work? Will have to exchange for another after Christmas since these seem hard to find lately. I tried it at the office downtown and it worked great w/o an additional antenna. Tried to use it once the other day on the bike. I put it in my jacket pocket and clipped the antenna to my collar. This did not work to well. The antenna needs to face southwest and when I was going west the signal was sporadic. The earphones did not feel comfortable and the volume needed to be constantly adjusted depending on my speed, which meant I was jacking with it while doing 70 on IH-10. Not fun. I finally clipped the antenna to my clutch cable, the reception was better. I got home stuck the antenna to the top of the windshield with the suction cup. I also bought headphones that clip over the ear and a CD case attached to the tank panel. I will try this set up when it warms up a little. The XM is great. I've had it since they first started and have not looked back. (never listened to sirius) However, only had XM in the truck. MyFi works great in the house with the home antenna and I finally have been listening to XM on my home theater system. The home setup is "quieter" so I have to turn the stereo up more than a regular CD, DVD but no problem. I have not tried the FM Modulator, don't really know how it works ditto with the "recorder".
After my first trial run I definately want a setup that will easily adjust the volume. JM already has the volume switch included. I was leaning more towards the rumble speakers but the do not include the volume control and they run about $300 but they do have an audio box that can be added (which is about the size of an altoids tin) that will control volume bass, treble...., for about 2-300 more. so both would be about the same price
