In gas carts, the sound has to be turned up too high and disturbs anyone you come near. It works better in electric carts. However, even though we have had a radio/xm in both types of cart we really didn’t use it much. I guess we are one of those rare couples who like to talk when we are together, or talk to whomever we are riding with. So we only used it when we were alone anyway. IMHO, it really isn’t worth it. Use your bluetooth earbuds and smartphone when you want music.
