My 2008 GS450 is plagued with the same issue on the same side. Heavy rain -> condensation -> HID ballast blown. This has led to the costly replacement of the HID ballast three times (!). The design of the assembly is poor in that if water gets in there at all, the ballast gets soaked. I tried the dessicant packet idea as well but it's not going to work. I noticed the rubber seal/weatherstripping at the edge of the engine bay over the headlight assembly is discontinuous, perhaps due to age, so I sealed it to prevent water ingress. I just used Gorilla tape at first, then some new weatherstripping. I can't guarantee you have the same issue but maybe worth having a look. So far so good for me anyway.

Paul: The MML can read playlists (.m3u files), but you can also just load up folders of tunes. It does display folder, artist and track names, but this may depend on the GS model year. The instructions for setting up a USB drive properly are a bit involved, I haven't had time to set it up properly yet. Regarding VAT/Duty, I'm in Ireland and was not charged any VAT or duty. However, this is the first time I was not charged on acceptance of a UPS delivery from the US. It's a small box, you might be lucky too.

Works perfectly with my ML system. I have a 2008 GS450h.

I just installed the Vaistech MML in a GS450h this morning and didn't know where to earth the unit either. I did find that putting the unit behind the carpet on the driver's side works well, it's much less hassle than behind the head unit or in the centre console box... I got the idea from this video (see at 11:20): https://www.youtube.com/watch?v=-tA0W4hJg0Q It's simple to get at later it if needed. By the way programming the MML may take a couple of tries, mine did at least. Unhitch and reattach the power harness between attempts. Eugene at Vaistech was really helpful, in case you have any problems.
