Pros: 1. The FM transmitter is very strong. Other reviewers complain that the transmitter was not good, but I find that mine can even overpower weak radio stations. I have a Monster FM transmitter, and it is not nearly as good as the T505's.
Cons: The unit is difficult to use when I have to put down my sun visor. That's not really the unit's fault, but it is the one time it's not safe to use when driving.
Pros: Battery life in this thing is great. I live way out in the boons and its nearly a 3 hour drive to the city, I have music playing the whole way there, while I'm there, and the whole way home on the weekend and doesn't come close to killing it. When making my usual rounds, it lasts for weeks. Was very easy to set up with my i9000, reads out the numbers as they come in, all buttons work with my media player on my phone.
Cons: FM transmitter quality is hit or miss, with some fiddling you can get it to be decent, but if you are a sound nut you may not be satisfied, but I cant comment on how much it may change from vehicle to vehicle, I've only used it in my 06 Impala/stock stereo. Its substantially louder than using the aux cable, but the quality suffers.
Pros: The battery lasts for a ridiculous amount of time. I use it for calls and for music streaming to my car radio. I took a road trip, this thing hadn't been charged in months, and it lasted for a good 7 hours of continues use on my summer vacation. The music quality is not to bad, not CD rate, but almost.
Cons: If you live in a big city with lots of radio stations, it can be a bit difficult to find an open, unused radio station to broadcast to your radio with zero interference.
Summary: Sound quality isn't great, but is good enough in most conditions. I drive a full sized pick-up which is noisey at speed. Most of my conversations are no problem.
Pros: Easy to use and set-up, doesn't need to be recharged often, works with my blackberry mobile charger, has more functions than I need. It does a very good job. I have had it for two years now. It came up on a NewEgg discount email this week and so I bought a second one for my wife's car.
Cons: Has more functions than I need. Buttons are a bit confusing if you don't have the manual with you in the car. If you hit the wrong one accidently or hold onto one for too long, it can be a bit of a pain, unless you speak the language you just changed it to. :)
Cons: Terrible microphone. My voice sounds like I am underwater to person I am speaking with. Controls are difficult to master. Cannot tell if unit is turned on as it does not stay lit. Finally had to order Jabra based on reviews on that product.
Pros: Streams my ipod touch music through the FM stereo! Verbally announces FM station, and when to pair up Bluetooth.
Cons: Can't tell if it is on 1/2 the time. MUST make sure music is coming from its speaker before turning on FM, or often does not work. Often have to change the station on a long trip, and re-tune the radio. If I use it for music from my ipod touch, I have to check to see if my phone bluetooth is functioning, and it usually is not. So I have to turn off the ipod to use the phone. Probably easier with an iphone.
Pros: I have been using this for about a month and I love it. It works better than I expected with my iPhone 4. One tap of the phone button and it automatically activates the iPhone's voice control feature, which I love. The sound quality is pretty good when streaming Pandora to the radio with it. The mic works well with speaker-phone use and the device quickly scans the FM band for clear a station to broadcast to. It announces what station to turn to when it finds a clear ...
Cons: Only one con. It only has a cigarette lighter charger. There is no wall adapter to charge the device inside. If you have a car where the power points shut off with the key and you aren't making long trips, it is a hassle to get it fully charged.
Pros: I have not yet received this item. I ordered it Friday, and it's shipping to me on Monday. However, I noticed in the specs AFTER ordering it, that this version of the T505 lacks EDR support. There is a T505 on this site that costs only $7 more...I changed my order to that one.
Cons: EDR triples the bandwidth of Bluetooth. this may not be important with regards to a speakerphone. I called Motorola, and they told me the main difference between them is the range. I did some research, and I don't think a lack of EDR will affect A2DP audio streaming too much...but I'd rather have the newer/better model.
