Max 2 Bluetooth Questions

I'm thinking of upgrading my 9500 to a Max2, largely because of the bluetooth capability, and because I'd like to mount it on my motorcycle. The problem with a motorcycle is that the detector is largely out of sight for the visual alerts, and the aural alerts can't be heard. There is the HARD system, but that's yet another thing to attach to the detector/bike AND my helmet and I'm not interested in it.

I already have the SENA 20S comm system mounted on my helmet which communicates via bluetooth to my iPhone 6. Questions:

1. Will the Max2 pair with and provide audio directly to my Sena 20S?

If not......

2. Will my phone pair to both the Max2 and the Sena and communicate with both at the same time?

If not, I'm done. If yes, then.....

3. I assume that I'll receive Escort Live audio alerts in the helmet from the phone to the Sena, but will alerts from the Max2 travel from the detector to the phone and then to my Sena/helmet? If so, that would be a pretty sweet wireless connection for alerts from the detector to the helmet.

Basically, in my helmet I hear any audio the phone puts out, but I'm not sure that I'll receive alerts in the helmet from the detector via the phone.
