Hi, I have a Map60C also, sharing the same goodies and badies. The
lack of BWC and XTE sentences is totally uncomprehensible, specially
when the 60C is sending a plethora of useless proprietary sentences.My
Autohelm 2000+ simply doesn´t work with the 60C, and I regret having
disposed of my Map76, which worked fine, having the afore mentioned
sentences. Let`s hope someone in Garmin someday take notice of
customer`s needs.I look forward to see that day coming. Otavio
Almeida.
