[MENTION=5906490]roystervi[/MENTION] : Toast doesn't go looking for songs by itself. It extracts this info over an API which Poweramp uses to deliver this info to Toast. Hence, whatever can be seen and played by Poweramp should show up in Toast. In my case, it makes no difference at all if the mp3's were found on USB, Inand or SD card. By the way : a new version came out where the user has much more control over the appearance of the Toast (font size ect) as was struggling with Toasts' size.

Also : you do realise the radio APK of a KGL device will not work on an AN21, do you ? :)

[MENTION=4674232]wanxu[/MENTION] : looks fab. Keep us posted !

[MENTION=6311672]rgrfish[/MENTION] : you're using a KGL/Huifei device too. I remember reports of bad radio reception due to cold-solder joints between radio tuner and antenna plug on these units, specifically a large coper-woven braid that wasn't soldered correctly. Also, if your car has an antenna with an amplifier (.... if your car antenna requires power, you've got one of those for sure), the issue might be a failing signal amp in the antenna, or a failing power line to that amp. Easiest way to check for this : disconnect the antenna plug and provide a different "antenna" (a piece of rougly 3 feet of electrical copper wire will do for this test) and use it as antenna : tune in into a stronger radio station, and see what happens. If the failure is gone, your antenna and/or antenna amp is the most likely culprit. If the issue is still there, the problem must be found inside your unit.

[MENTION=748902]Kidmet[/MENTION] : If you're saying this issue started after resetting, it MIGHT be connected to the "swap SD" setting (settings>extra settings (code 123456). Look at the "Switch SD 1 and SD 2" and the "Switch SDcard" settings and see if that changes your situation Possible something went coocoo there). Be sure the used SD card still works (yeah I know it's improbable, but these things sometimes die at the most idiotic moments). If everything else fails let us know. Normally I would suggest a firmware update, but you need the SD card to be accessible for that.

[MENTION=1971803]cbergs[/MENTION] : No, you can't backup a flashed mcu file if it's not in the etc location and if it's flashed in the mcu, you can't retrieve it. Have a look at the yandex file repository : there's LOADS of mcu's there ! I own that same silver-type AN21 unit by the way. I wonder if the 4.2.15 isn't an Xtrons-specific MCU (I guess you're using an Xtrons 630 ?). If so, can't you get the file from Xtrons ?

I'm a bit puzzled about what that Landu BT OBD is : when I look at the MCU code you give (ending with 2101), this should point to a BC5 BT board. But BC5 boards should not be able to pair to a BT OBD. When you pair it to your unit, does your unit see the OBD as "phone" or litterally as OBD ? Because afaik, only the BC6 shows the "OBD" option when pairing. (.... ? simply said, I don't understand how you can pair a BT OBD with a 2101-ending MCU).

No, at the moment, I do not have any BC6 modules left, however, I'll ask my seller if he still has them available (I'm pretty sure he will) and pass you the info to get it for yourself.

Still I'm VERY curious about the hole situation. Do you have any additional info on that ? But I'm pretty sure you do have a BC5 thing, as it's impossible to get a BC6 board to run with a BC5-mcu (believe me, I tried) ergo if your BT still work, it has to be a BC5 .... and that Landu Thing must be something special compared to other OBD BT's as it mimicks a "phone-like behavior" to allow BT pairing. Does it have a BT-pair code ? Because the BC6 solution pairs without BT-pair code.

In other unrelated news, I've received that DA-350 microphone array yesterday. Sadly, I botched up my Iso-connector on my electronic testbench so I need to replace that first. Once that has been done, I'll experiment with the array on my spare AN21 and I'll keep you guys posted about the results.
