My sister has an older car that has a tape player and always has her phone on speaker to listen to her music instead of the crappy radio stations

Who is hate having to get out and miss part of the conversation when he comes to my radio this was pretty easy youre plugged it in yet turned onto a channel that wasnt active turned on your phone and you turned into the radio and you got your radio through your phone i think it actually sounded better in my phone that it did to my car

After charging the battery you set it to an unused fm channel match up thst channel on the car radio and it then you can talk using your speaker or play your music through it

Now when i call my husbsnd with the fm transmitter attached he can hear me and i can hear him just as clearly with the windows up or down
