We have had 20s for a while now. Honestly, our needs and setup utilizes a fraction of the a ailable functions.
initially, I became less excited about the 20s but via others advice, accomplished resets after a recent firmware upgrade. This task really made the 20s very nice.
When not in multitasking mode, after the initial intercom connection, which we accomplish at the start of a ride, or after powering the Senas up, the intercom connects almost immediately with no isdues.
I plan to revisit multitasking. One downside being, if music is playing, and your passenger sings along, the intercom kicks in...
Realize also, if using an IPod, and the Spyder radio / interface and a Sena Dongle, the Spyder will limit the IPod volume to 50%. Because the IPod volume is reduced by the Spyder system, often, you increase the Sena 20 volume. Because of this, between songs, you might have a slight hiss, but is not an issue.
