I CAN'T USE THIS DEVICE AS I CAN'T TUNE IN 99.3 ON MY RADIO.
I WILL BE RETURNING THIS ITEM.

Comments about Jupiter Jack™:
This works well with my inexpensive Net 10 phone that is less than a year old. For the nicer Motorola Razr that is 3 years old, I could not get it to work at all - just static on both channels. Great concept!

Comments about Jupiter Jack™:
In general, an excellent way of using your cell while concentrating on driving. It does have to much static, though you can hear the other person through your car speakers.
