I had the same problem with my module. Turns out that mine was an early one in production. I called novak about this, they told me to cut part on the circit board out with a dremal tool so that the last two pins from the radio will go into the module. (The last two pins are not used anyway with this module.) I did what novak said and it worked perfectly. I've had no problems at all.
