@ p64: Does the dension Gateway 300 provide navigational (folder name) and file information (e.g. ID3 Tag) by the original headunit display, just like if you were using an mp3 CD in the CD player (no satnav!)? Pictures would be welcome

How about the controlling? Is this also working by the steering wheel?
For the installation, is there anything else (connecting to ground, ignition etc.) needed except for connecting the Gateway 300 to the CD changer connector of the original radio?
Because I'm seriously playing with the idea of buying one of those, including the Bluetooth adapter (BTA 1000). I asked my local dealer about the original Honda hands-free unit for mobile phones and he said it would be at about 400 Euros, including installation. I don't think the installation of the original hardware will be lots easier than installing the Gateway 300 + BTA 1000 (without installation approx. 220 Euros) and with the latter one, accepting or rejecting a call can even be done by the headunit or steering wheel. Additionally, one can connect an USB mass storage device if wanted, just like you did. So the dension solution is money well spent IMHO.

Ok, thx to seiken, the displaying questions have been answered. There's no useful information displayed on the original headunits display. In fact, everything else would have surprised me, as it comes through the CD Changer control and usually this connection doesnt provide track information by the stock CD changer anyways.
I made a mistake in my original post, the gateway 300 + BTA 1000 would be approx. 260 Euros without installing. The other price was for combination with the Gateway 100.
Another thing that seiken mentioned was that he has serious echo on the calling partner side via the hands free function of the BTA 1000. So I looked around and got multiple feedback from local dealers. For additional description see
