Do you check setting for input-output interface on new Garmin 60CSX? May be it is cause?
Com cable? do you mean serial cable connection? nRoute has same problem whether connected usb or serial. will check settings on my 70cx, maybe WAAS is a problem???.

If you have nRoute working no problem, could you tell me what gps devices you have tried and worked successfully?
