I've been using a Window Valet plugged into the OBD II port without problems for over a year. I'm now trying to also use a range AFM disabler (current firmware version) as well using an OBD II splitter. The splitter I bought has power on/off switches in case I needed those. The Window Valet won't work when plugged into the splitter whether or not I have the AFM disabler plugged in.

Anybody using the Window Valet with a splitter without a problem? If so, please tell me the model/source from which to buy. Thanks.
