I had a Fiscon for 2 years. Then I replaced it with the oem bluetooth unit.
VW oem unit...
1. Lovely clear reception.
2. Far, far less interference / feedback etc both when in use and not in use.
3. The steering wheel buttons all work exactly as they're meant to.
4. All my texts appear on the MFD and can even be read out to you!
5. Nice selection of ring tones
Fiscon...
1. The opposite of all the above!
2. Sounded shrill & unpleasant in comparison
3. The steering wheel buttons don't all work as you expect
4. The MFD displayed a random assortment of texts, they may or may not appear, some came through, some wouldn't, some old ones kept coming back (wtf?)
5. I never got to the bottom of an issue with the radio / music occasionally not coming back on automatically after a call was finished.
To be fair to Fiscon, I never updated the firmware, but in my experience there is simply no comparison. The VW oem one simply works all the time, as intended, sounding better.
You can pick them up on eBay - I think there's a Polish seller (proper business) who sells them for about £200, so it's cheaper than a Fiscon!
