FWIW, just my 2 cents worth, it takes less than a minute to pull the XM radio head and store it in the locked center console or the saddlebag, The quick disconnects the 3.5 plug, power cord and antenna and you are done. If you want to take the dock off the Ram mount add another 15 seconds. I got about $25 in my ram mount. Now if money is no object and you want to spend big bucks on a TPS/XM/GPS system go for it. I have a small used GPS unit mounted as well. Whenever I stop I always pull them off and store them under lock, easy peasy. I got less than $50 bucks in my two systems, its your choice.
