I have the ca2791bt for two days and I am very satisfied since it is essentially the same as the ca2778bt which I enjoyed for about 5 years until it met an untimely death. The only issue is that after the 3rd year of intensive use, the buttons faded on that one. The only differences are the second USB charging port which I haven't tested how powerful it is and that it now has 4 RCA outputs for an amplifier. Bluetooth connects immediately, you hear and are heard perfectly. The sound is very good and the button is immediate and clear, and the 4x40 is valid. The radio is perhaps the best I have ever had in a car in terms of reception, it just has only 3x6 memory presets in total. It recognizes folders on USB and SD. The buttons have 2-3 functions each, so it requires a bit of reading or wandering for familiarity, but once you learn it, you can quickly get your work done while driving. At this price, I can't imagine someone finding something so decent in quality and practical.
UPDATE: After ten days of use, all of the above is confirmed. The equalizer, although simplistic, does its job just fine. The only observation is that the charging port is weak and takes many hours to charge a phone. The time resets itself even though the saved stations do not.
The buttons seem improved in quality compared to the ca2778bt.
And one observation: as with most portable devices, the MP3 tracks you intend to play via USB/SD card must be up to 196kbps recording density, otherwise it skips them. So if you have some, for example, 320kbps, you need to convert them through some online website and re-record them on the storage medium.

I also got the ca2792bt which is equally good with the following differences: 1. a bit more user-friendly regarding the equalizer 2. it has a separate volume for calls or music which is very useful 3. it also has an AM band on the radio
