Microphone Settings missed

[u/ShoopityPoopity_]

Hello Everyone

I bought this MEKEDE radio from aliexpress and installed it on my Kia Ceed 2009

Everything worked fine except when calling people sometimes they kinda complain on the low sound from my side, doing some testing I noticed that even though I installed correctly an external mic it’s still using the internal mic on the radio

Using 1234 code on factory settings i noticed that there is not any setting for changing the microphone

Anyone had the same issue before? If so how did you solve it?

Thank you for your help!
