MP3 Player FM Transmitter + Bluetooth Carkit with USB/SD Slot and IR Remote Controller

Pros: This gadget is an absolute must in California, since it's a law to be hands free with cell phones now. It does everything it's advertised to do, I love the small remote controller that came with it. I makes my 95 camry feel as though it's rolling with the cutting edge technology

Cons: You need a good radio receiver, I've tried these in cars that have junky radio receivers, and likewise the sounds quality sucks. Luckily for me, my car has a great radio receiver and both music and phone calls work awesomely.
Another con, is you can't control where the songs start, I wished there was some sort of file organization that can be seen with the LCD

Other: This product is simply the best for bringing your low tech car without bluetooth to the modern world. With it, I can make calls and talk to my friends and family all with a push of a button.

Pros: - Excellent quality of sound (it seems like a real FM broadcast)
- Full FM tuner range. So you can select the best frequency for sound quality improvement.
- Excellent mic quality (for handsfree function)
- Intuitive interface, that makes it easy to use during driving

Cons: - Does not have shuffle function, so you must listen the songs in the exactly order you put it into the memory card
- The remote control only works in certain position, making it difficult to use during driving

Other: It´s an excellent handsfree apparel, with excellent quality of sound (even receiving or transmitting it), simple to use and very intuitive.

Pros: Great equipment, combines several technologies into a single item, very useful for people who spend much time in the car in traffic or working with the car.
Bluetooth is very easy to use and sync with your celphone

Cons: Display with poor visibility, material that was built is weak ..
It has a playlist and other basic functions found in any basic player.
After some time, support that connects the cigarette lighter is no longer fixed, making it difficult handling

Other: Great gadget, with good price and number of functions, and easy handling.
A wonderful choice of hands free

Pros: - Easy too set up and use - Sound quality is OK for an FM transmitted signal - Bluetooth function works well, no feedback or echo and the sound through the cars speakers is clear. No complaints from anyone on the other end of the line - works well with SD cards and USB drives - it remembers what song you were listening to when it is unplugged starts than song again when you plug it back in

Cons: - sometimes I get a small shock from the small metallic jack on the side when I insert it into the cigarette lighter - screen that shows the song title and artist is far too little to read while driving - MP3 player does not appear to support random play or folders, it can get tedious listening to the same songs over and over in the same order - I wish it had an input jack to also play my satellite radio through it

Other: Works really well for a bluetooth interface with your stereo. I think this works as well as the one that is integrated into my Prius as a factory option. Lack of features on the MP3 player are the only downsides.

Pros: MP3
- It has shuffle functionality
- I have tested and works with:
1Gb SD
4Gb SDHC
1Gb Pen drive
8Gb Pen drive
- I have used installed 839 musics, and works fine
- Remote control fully works
FM Transmitter
- 0,1 MHz step
- clear signal
Bluetooth
- Works as expected. Once paired, it always detect and connects when both phone and carkit are on.

Cons: MP3
- Poor information manual, but you can easily operate it. For example, does not explain how to set it to shuffle.
- Did not recognize my WMA files. But I don't care about M$ formats. MP3 is enough.
FM Transmitter
- The box say "clearscan" but I did not find this feature. Locating a new frequency needs your full attention.
- Some frequencies may suffer interference from the mobile. This is not a limitation of this carkit. It happens to all devices.
Bluetooth
- The microphone could be more sensitive. Anyway, if I speak louder, the other side could here me well.
- The blue led is too bright at night. I put a stick on it. There, I fixed it! See the picture I've uploaded.

Other: Best cost-benefit carkit (mp3 player, fm transmitter, bluetooth). Buy it!
My friends really liked it as well.
Arrived in Brazil in 21 days. No tax invoiced to me.

Pros: Worked first thing out of the box, no issues pairing it with my cell phone. Sound quality of the FM transmitter is on par with some of the better ones I've used. Hands free sound quality is pretty good, the people I talked to seemed to think it sounded alright on their end.

Cons: Shuffle feature (press and hold CH button) is not very random, it seems to have its favourite songs and its not smart enough to know if it already played a song. I actually had it try to play the same song twice in a row. Can't seem to get the auto-answer to work but I'm not sure if that's a limitation of the device or my phone. I have my phone set to auto-answer when a headset is connected though. Screen is really small, not really helpful for displaying what song is currently playing unless you stick your face right up to it (kinda hard to do while driving).

Other: If you're like me and your city has made it illegal to talk on your cell phone without a hands free unit this is a cheap fix.

Pros: Quite a good device and does play MP3 Crystal clear through your stereo with good bass and no distortion, just as good as FM radio. Nice at night, cool blue lights on the display.

Cons: The MIC is awful. I found myself shouting just to be heard on Freeway trips. I ended up making a modification so I could clip the MIC to my shirt lapel, and it works great now. (Will post pics if interested)

Other: Overall, for the money, you really can't go past this device. Very well made and looks much more expensive than it was. The MIC issues could be my distance from the dashboard (I'm very tall s sit far back from the wheel / 12V outlet) but I still would have expected better from the MIC.

Pros: seemlessly allows my adp device (tmobile g1) to stream pandora via bluetooth to FM. Sound quality is quite good, switches from music to phone calls automatically and quickly, then back again after call. Has a remote as well and remembers fm frequency after power off

Cons: even after boosting volume and bluetooth volume via mods on my phone, it is apparent that the unit itself has a rather limited volume over fm; have to have volume at roughly twice the level of the cassette adaptor I used previously. Essentially, I traded the muddiness and popping of the cassette adaptor for greater background noise and the ocassional pop as the audio connection switches if tracks aren't seemless. EQ settings dont seem to make any difference

Other: popping between audio connections and background noise would be minimal if max audio threshold was higher, otherwise quite a good buy if you hate wires.

Pros: SUPPORTS ADP! aka audio streaming over bluetooth
pairs quickly
less cable clutter
excellent audio quality
powered by cigarette jack
seamless switch between music and incoming call.

Cons: volume is rather low; audio quality over cassette adaptor is somewhat offset by having to crank up volume and increase background noise threshold
doesn't maintain constant audio connection (pops if there is a gap between songs)
eq settings do nothing as far as I can tell
often doesn't transmit call audio if music hasn't been playing first

Other: cut down on cables, lets you charge your phone and talk/rock out at the same time

Pros: In my car worked very well, so much the sound of the MP3 I found a radio frequency had almost no noise.
The service functions on the mobile phone via (bluetooth handsfree) also work well. Very easy to pair with my phone, a Nokia E71.

Cons: The names of the songs on the display could be larger.
Random functionality does not work right, always repeating the same tracks.

Other: My 5 year old daughter speaking from the back seat of the car and was perfectly understood by those who were on the other side of the phone.
