Does anyone have experience with using a Harman Spark wi-fi cell receiver? My wife needs to upload large audio files on the road and using her cell phone as a hotspot with her laptop does not perform very well. The Harman manual says the unit needs to be plugged into the OBD-II port.

I don't have experience with the Harman spark, but I was reading their web site and I wonder if it's true that it only works with the ignition on and that it stops working when the vehicle hasn't moved in 30 minutes?

We've been looking at the winegard Togo and now I wonder if there is the same restriction.

Thanks! I believe that is true based on the YouTube review I saw. I'll checkout the windgard
