I hope someone out there can help me with this issue. I have a 4 to 5 year old M12, I have glitching problems on an out door track. I have RX481 wireless attenas in both cars, at a distance they lose signal and bad things happen. I had wired antennas did the same thing thats why I switched to wireless. I'm considering a new M12 S Super but hate to throw good money after bad only to find that I have the same problem with the new radio. Thoughts???
