This is a excellent unit for the price. It does have its pros and cons. Pros: 1 The unit has two SD card slots. One for GPS and one for multimedia files. 2 You can Nav and listen to music 3 You can send video to a rear monitor. 4 The disc drive play MP3's 5 Rear camera connection 6 The nav is FAST!
The cons. 1 When the car is off and the radio is off and you are playing mp3's from the sd card slot it does not return to the last song played when you turn the unit on again. It starts over. 2. NO DIRECT PLAY you have to scroll through the songs. Its software does not give you the folder names and songs.(sucks) The direct play is a big issue and the software in the unit to view songs. It will return to the last song played if you are using a cd or dvd. But it is slow. and you still don't get to view the folders and songs. But for the price, you can learn how to navigate through your music. Overall, great unit
