I was in a search for car mp3 player for a long time, but couldn't find the one that met my needs. There were three things I was looking for: able to play through aux port in my car (much clear sound compared to fm transmission), able to view song and folder name, able to resume the audiobook where I left off. Soundfly Aux does it all and more. Here are the things I like and I don't like:
1) Beautiful design: Matches perfectly with my silver interior dash trim, actually it looks like it is part of the car.
2) Easy set-up: Plug in to the cigarette lighter, plug in the aux cable, put the SD card in and it starts to play music immediately. Although there are six buttons on the device itself, there are so many functions, so keep the manual with you until you get used to main functions.
3) Song and file info: While music is playing, you can see the song name, artist name, folder name and play time info on the screen. When you press the NAVI button, you see all the songs in the folder, then press the menu button, and you can visually go through all the folders. This is a neat option that I wasn't expecting.
4) Bookmark: This is the main function I was looking for and it is so easy with Soundfly Aux. Push and hold the play button while the music is playing and it bookmarks the exact play time. It is better to use this function just before you leave the car.
5) Contrast: It is great that there is a contrast option, I can get a much better view of the screen, when I increase the contrast during the day time.
6) Remote control: You can use all the functions with the remote. It helps a lot to keep an eye on the road.
1) Not able to play DRM audiobooks from Audible, only mp3: I just did a google search, audible and drm, and found the necessary software for conversion, but still wish it could play natively.
2) Fast-forward is only through the remote control, so don't lose the remote.
3) Just the screen could be better looking, but I think they did it for anti glare purposes.
Apart from that, this is the only car mp3 player in the market with all the functions I wanted and I am very happy that it works as expected. Highly recommended!..
