The IntelliCast FM Transmitter + Car Charger worked but fell short in 2 areas for me.
1 - the signal sent to the radio required me to turn the volume way up in order to hear it over road noise and, like some old car cassette tape players, this is very bad if you have to change input sources.
2 - I liked the feature which allowed the use of a micro SD card, however when the vehicle is turned off and then restarted the music returns to the start of the of the playlist folder. The unit remembers the selected radio frequency, why not the current music track? Probably not a problem if you stream over bluetooth, but a deal breaker for me.

Here my thing about this product--it did not let me choose the frequency on the radio. As soon as I plug it in it came up with the radio frequency it's self and frankly it's not the best , clearest OR the one I was using with my old bluetooth transmitter. Is there a way to change it to a different frequency??

I wasn’t really sure what to expect with this product I but I was pleasantly surprised! It works very well and sounds great! I drove from Arizona to California and the signal was never interrupted by another radio station (which I thought it would be) and the sound quality was better than if I use an auxiliary cable into my radio. It’s very easy to use and set up. And once it’s set up it automatically connects to the phone when you enter the car and maintains all the settings you left on it before. This has really helped me for long trips because I’m able to charge my phone and listen to music, I couldn’t do both before because my iPhone only has the one lightning port. This is a quality item at a great price that has really helped my vehicle become more comfortable and I’m really happy with my purchase!

I love this little device. I already had another type for my car, but got another car so I needed a new Bluetooth. I am so glad I got this. It’s louder than my other one and it can make calls clearer. I love being able to put my micro chip in it with music loaded on it. I already told my kids about it so they could order the same one. Very happy with my purchase!!

This little device is awesome! Simple setup in couple minutes and so easy to use once setup. My car currently has blue tooth capabilities for phone; but only for phone. I can't use it for music on my phone; nor Audible. This device resolves that it - it works for EVERYTHING I need. So long using the build in car limitations! This device lets me listen to my music, listen to my Audible books, answer the phone, all of it. Well worth the cost!
