Not sure if others have had the same problem but I recently had my Ws4 and black coil updated to version 5. Did not update the hf coil as consensus was the hf coil did not need updating.
Black 9 inch coil works a treat with no issues, tones are harsher but little price to pay for the extra functions. However the hf elliptical coil is unusable. It turns on fine then loses the connection then reboots and losses connection again soon after.
I have reinstalled the coil several times and even kept coil plugged in when testing but still suffers from signal dropout.
Worked spot on with 4.1 but would rather stay with v5 if I can.
Have others had this problem? Should I update again and include hf coil in update?
Would be interested to hear others opinion. Thanks
