I just bought the SMH10, and was hoping to hard wire the radar to the headset, while having phone and music from the phone bluetoothed. I now know that THAT isn't going to happen and still have my music, but..... I if I get the SM10 dongle, can I - 1.) Bluetooth the phone by HST only, 2.) Hardwire a mp3 to the headset, 3.) Hardwire Radar to the SM10, then 4.) AD2P the SM10 to the headset?
I know I'm a little late, but I've been doing some research on this and ran across this post. Here's what I found out:
The SMH10 allows two HFP channels and one A2DP at the same time.
- The SR10 uses HFP
- The SM10 uses A2DP
- A smartphone uses both HFP and A2DP (although you can connect only the HFP part using mulit-point pairing)
- Some GPSs use A2DP, but ones like the Zumo use HFP (beware that most car-type GPSs with bluetooth only have a BT receiver, not a transmitter, made for connecting your phone to the GPS, not the GPS to something else)
- based on the built-in priorities of the SMH10, if you hard wire anything to the headset using the 1/8" input, you kill the A2DP input to the headset.
- and the intercom preempts all A2DP signals, as well as anything from the 1/8" jack
So, given that, you can connect a phone (with or without A2DP), an SR10 (or HFP GPS, or 2nd phone), and, if you didn't connect the A2DP part of the phone, another A2DP device (iPod, A2DP GPS, SM10, etc) all at the same time.
With the SR10, you are supposed to get input simultaneously with the intercom (and the phone?), although the docs seem a bit vague on this. Its made for a two way radio, so the idea is that you can talk on the two-way and the BT intercom at the same time. The downside is that the SR10 is mono-only because of the HFP protocol, even though it has a stereo input jack.
The new v5 manual has some additional diagrams showing simultaneous connections to a phone, SM10 and SR10, as well as various GPS diagrams, but its still a bit confusing because of differences with GPSs, etc.
Hope this helps.
