Hello. I have a VORDON HT-869V2 car radio, purchased in spring 2017. The radio has an integrated bluetooth hands-free kit, but the built-in microphone is very weak, it requires bending and speaking loudly to the radio in order to communicate with the interlocutor at all. I noticed that the currently sold model of this radio (https://vordon.pl/product-pol-108-Radio-samochodowe-HT-869V2-mikrofon-zewnetrzny.html) already has an external microphone in the set, which I guess is for the task of eliminating the previously diagnosed imperfections of the product.
I spoke to an authorized service center by phone and the Lord (I have the impression that he is fresh in the subject and without panache) informed me that if a model was sold without a microphone, there was no jack input and nothing could be done about it. He described the models sold in 2017 as the older ones.
My question is: If in fact the radio does not have a rear jack in for the microphone, does anyone have any experience or idea how to connect an external microphone to this device? Maybe some modification?
Apart from the aforementioned warranty, you can open the radio and solder the microphone directly to the built-in microphone, or you can mount a jack socket on the back of the radio and connect it in the same way.
