I can’t say this is the exact model but I remember it being around 17 bucks and this is the general style. I have one in my work van and one I move around between my F150 and my old Wrangler. I bought a $50 radio for my Cherokee and while it’s not great, it has blue tooth built in. I also have one in our camper because it has an am/fm radio with a CD player and speakers inside and outside of the camper, so it’s cool to be able to listen to good music when we’re using it.What kind of transmitter are you using?
Ones I have tried never have much volume.
