I love my SN-10, but don't like any of the audio's.........I want up only audio. Can't stand an audio that never shuts up! When the audio comes on, it means I'm entering lift, when it goes off, it tells me I'm leaving the lift...........don't want or need anything else in climb or cruise mode. I have flown with the Borgelt 300 or 400 along with my 10 for years. The 400 and 700 have a Backup 6 volt battery. Nice feature, got me home the day my battery lead broke.
