I have replaced the original CD / radio my Alfa Romeo Mito.
Sonically the DPX405BT located at a distance from the standard Blaupunkt.
I have the DPX405BT combined with the "Helix P236" and "Helix B12 DSP".
Even without power amplifier supply these components a damn good and especially
clean sound and crisp bass.
Among other things, I use a "Verbatim Store'n'Go 16GB Netbook" USB stick, which is recognized and read in a few seconds, although it currently contains about 12GB MP3 titles.
The problem is that the fuse blows, if the start a USB stick is connected,
I did not. But it was installed the Firmware Version 3.04 also ex works.
Furthermore, the previous speaker writes that instead of folder names only Folder1, Folder2 etc. appears on the display. Also this problem I can not determine with my radio. First, he shows me the folder name, and only then, when I select this appears for a second Folder X and playback starts.
The Bluetooth pairing is also fast and above all simply vonstatten.
Both Bluetooth streaming and telephony works perfectly with my Nexus. 4
In my eyes Kenwood delivers a very successful and effective Double Din Radio, which has hell of a lot for that price.
In my case, I had to buy additional a radio mounting frame and an antenna adapter.
