Query: had problems with this one

I bought this to replace a stolenMonster iCarPlay Wireless Plus FM Transmitter/Charger for iPodthat worked very well. This model has some problems: The worst being anytime there is a quiet section playing, the transmitter completely stops working. If you listen to anything with any dynamics, expect to be interrupted by loud radio static when the device cuts off. Another problem is the size of the plug - if you use any iPod case or cover, it will not fit. You will have to remove it from the case every time you play the iPod in your car. It gets annoying if (like me) you want to use it every day. It has also locked up my iPod a couple of times, requiring me to reboot. Do yourself a favor and get the older model which works very well. The extra bells and whistles are not worth the aggravation.
