Query: Don't be taken advantage of!

This product was intentionally downgraded, so that the FM transmitter will only work if you buy the car kit. Now you can't take it to your office and use with your boombox, etc. Perhaps they think they will sell more hardware this way.However, in the days of advancing electronics we should expect better. Don't buy this product until they change it back! Don't worry, a competitor will soon improve on this situation!
