The "Active" Brodit Carkit, specifically the charger part, can blow out the USB port on your TyTN II, and you will need to RMA your phone. This is due to a missing diode, allowing the car to actually draw power from your device when it needs to. Obviously, the phone does not like that.
The problem seems to be dependant on wether your 'cigarette lighter plug' is positioned before or after the key contact in the 'power chain'.
If you have an Active Brodit carkit, CONTACT YOUR IMPORTER. They can identify if your carkit has this problem by it's serial number (at least the Dutch importer can, I assume other importers will as well). They should (and will) replace or fix the carkit for you by adding a diode and replacing the 1A fuse with a 2A fuse.
There are not a lot of units that have this problem, all of them are early units and are reported to have a serial number starting with M. But it's always better to call and check then having to RMA your phone. If someone who calls their importer to check their serial number could ask for the exact range of 'faulty' units so we can post it here would be great!
The original information came from the TyTN II topic at GoT

(sorry if this has been posted, I honestly couldn't find it)
I was (am) looking to find a nice holder (and charger) for my car for the Kaiser. I was actually considering the Active Brodit holder, but then stories started to reach me on another forum (GoT (dutch)) of several people who had their active Brodit's charger damage their USB port.
One of the guys on that forum contacted the tech support of the importer of the active Brodit. Apparently what happens is when you turn off your car, the car drains power from the Kaiser and this can break the holder and possible the the phone's USB port.
Anyone here have any experience with this?
