The sound system is VERY good. Both in performance and features.
I installed it in a 2011 Leon, previously I had a terrible Android screen with such awful sound that I thought the factory speakers were to blame, but I thought "before I change them, shouldn't I change the sound system first?"
With the DPX-7300DAB, the sound transformed, it reached a different level of performance.
The positives:
- It supports Greek characters!!!
You can see song descriptions/titles in Greek! Obviously, it will also support Greek in your phone contacts.
- You can connect 2 Bluetooth devices simultaneously and up to 5 alternately.
- Very good sound.
- Many sound settings (including advanced ones like Time alignment, Distance, Crossover, Subwoofer, EQ, etc.)
- Many display settings with colors, dimmer (programmable according to the time to avoid disturbance at night), etc.
- Digital radio included in the package, with its antenna (usually you have to buy the antenna for DAB separately)

The negatives: The Android app for controlling the system via Bluetooth on your smartphone is a bit lousy. You download it from the Google store and have access to all the system settings, but for playback via Bluetooth, it is better to use your favorite Android music player.

I have had it for about a month, for any updates (positive or negative), I will come back!
