Peugeot 2006 307 tape replacement no sound from parking sensor

Hi aleyküm friends, as I wrote in the title, I had a jvc brand tape installed, the parking sensor works, but there is no sound. How can I solve the problem?

If there is an original parking sensor, it will come from the speaker. If there is no original tape, the sound may not be heard.

Yes, it has original parking sensors. Is there another formula?

bluetooth apparatus would not be a problem, sir, I applied it to my 308 vehicle, the sound quality was quite sufficient. probably has no other choice. The original parking sensors give a sound from whatever eye object is detected.

Well, which apparatus did you buy, is there a bluetooth apparatus with good sound quality that you can recommend to me?
