I have a Dynavin in mine, installed by the previous owner, and I'm stripping it out to go back to OEM. Bad radio reception, bad sound quality, totally useless iPod control and screwing up the OBC is not an upgrade as far as I'm concerned.

The Huangilan looks marginally better but I wouldn't spend any money without a very thorough test drive.

If anyone in the UK wants to trade my Dynavin for a 16:9 monitor & BM24 radio module, PM me....
