I think my transmitter was made by Monster. Be sure to buy one where you can change the station it transmits on. I live in the NY area and frequently drive to DC, so I can tell you that it works fine in the car, but you might have to change the station every 50 miles or so. I have 2 Lincoln Navigators, one with an ipod interface and one where I use the transmitter. I am an audiophile, but I still don't find an appreciable difference in sound quality for 95% of the listening I do. Now back when I didn't care about hearing loss....
I chartered a Lagoon
410, and I called the charter
company ahead of time to find out the exact audio setup. With all the wind noise
, I could never have told the difference between FM modulated and directly connected. On the ball, I wasn't exactly playing at concert volume, so again, the quality difference was not apparent.
