So far no one has "Cracked" the XM system. They HAVE successfully "cloned"
receivers by copying the RCVR's ID to another like unit.
I personally own 3 of them...for $9.95 for the first one and $6.95 a month
for the other 2...just pay the freight, it's a good deal for less than you
would pay for a month's consumption of cigarettes or coffee at
Starbucks....Eddie
