donkaye Posted January 10, 2021 Report Posted January 10, 2021 I posed this on BeechTalk and I thought I'd do the same here. Given: Aera 760, GDL 52, Bose A20, GMA 35c Is it possible to bluetooth the XM Audio from the GDL 52 to either the Bose or the GMA 35c? Hardwire, of course, works to both. Bluetooth not successful to either. Quote
carusoam Posted January 11, 2021 Report Posted January 11, 2021 One of the challenges for BT (the teeth, not the talk)... 1) It depends on how far away the emitter and the receiver are... 2) What gets in between them... 3) The direction of the box with the antenna is... 4) A few Long Bodies with the GDL in the tail had difficulties getting the signal up to the front seats... 5) One big challenge was a piece of foil backed foam used to insulate the back wall... some planes had a piece of aluminum back there... There are a few slightly aged threads covering this topic... Is this anything like what you are experiencing? BT is cool because one source can feed multiple devices... where WiFi does a similar thing, but can only connect to one device at a time... (rough repeat, of stuff I have learned here) Best regards, -a- Quote

Only audio is missing. 1 Quote
carusoam Posted January 11, 2021 Report Posted January 11, 2021 Let’s see if @KLudwick is around... KL has some big G experience... and may know others with more experience... (sound challenge, wired connections work, blue tooth doesn’t, details in posts above...) Invite @Baker Avionics Greg to the discussion.... he may know some details as well... Best regards, -a- Quote
Aerodon Posted January 11, 2021 Report Posted January 11, 2021 Don, I can BT my cellphone audio to my Bose A20 very nicely. I tried the BT music audio from a GDL52 and a 52R (as apposed to the 'alert' audio) to my A20, and the volume was way too soft. I came to the conclusion that it was not possible. Yesterday my friend managed to get successfully get BT music from a GDL52R to his Lightspeed headsets. So at the next opportunity, I plan to go try by A20's alongside his Lightspeeds for music. Hardwire, no problem. Aerodon 1 Quote
LANCECASPER Posted January 11, 2021 Report Posted January 11, 2021 I have the same set-up with the Aera 660 and the GDL52 and I think the music goes bluetooth from the Aera 660 to the audio panel since the 660 is what determines the XM station I'm on. Quote

What audio panel do you have? My 760 pairs with the GDL 52, but the GDL 52 won't pair with the GMA 35c. The 760 can pair with one device and the GDL 52 with 2, but the GMA 35c apparently isn't one of them. Quote
DMM Posted January 11, 2021 Report Posted January 11, 2021 I have no personal experience with the A20s but read that the early Bluetooth implementation wouldn't allow music streaming. something about A2DP. I think that changed around 2015. 1 Quote

My airplane is getting some panel work done or I would walk out to the hangar to check for sure. I should have it back within a week. You may have to hardwire the 760/GDL52 and then connect the 760 via bluetooth to the audio panel. If you want to keep it portable so that you can move it to another airplane when you instruct, I believe Garmin sells a cigarette power cable that powers both units (760/GDL52) and connects them. Connecting bluetooth then to your headset from the 760 should work. Quote

My shop talked me out of a GMA35c and 350 when we were planning my initial upgrade in 2016 but am not recalling specifics from the “audio” pieces of those conversations.

gsxrpilot Posted January 11, 2021 Report Posted January 11, 2021 Usually the situation with Bluetooth is that there are limited "send" channels and most devices are limited to "receive" from a single source device. I'm not familiar with the GMA35c but you might start with an inventory of what devices/audio/streams are being "sent" over bluetooth and what devices/audio/streams are being "received" over bluetooth. You might just be out of channels. 1 Quote

I don't think so. The 660 selects the channel on the GDL and the GDL receives and plays the XM music - either hardwire or BT. Turn the 660 off and the music still plays. The 660 has audio out wires, but I believe they are for 'alerts' and messages generated by the 660. Aerodon Quote

Mscheuer Posted January 21, 2021 Report Posted January 21, 2021 Hi Steve, I can try. The PMA450B actually has two Bluetooth (completely independent) which allows connection to two devices simultaneously. This then allows the pilot, copilot, or passengers the ability to listen to two devices at the same time. For example, the pilot can connect their phone (music source or telephone) to BT1 while connecting an iPad to BT. Now the pilot can her ForeFlight audi alerts and hear his. USBc from their phone at the same time. or maybe the kids in the back wanted hear the audio from a movie they are watching on their iPad but mom and dad want to hear their own entertainment, they can! All in all there are a total of 27 music distributions that can be selected, and it is VERY EASY to do. Hope this helps! Mark 1 Quote
