I have installed this unit in 4 unmarked police cars so far to date and no real issues. Only problem ever encountered was the double female connector between the data cord and handset. Found one and back in service. Easy install and if using LED lighting you can use several of units on one switch. Going to continue to use theses for unmarked vehicles.

I was looking for a new siren/and strobe lights kit for my car I found ETD to beat any Price's around. I ordered it the one day an went down to pick it up 2 days later. I also ended up going back and buying two more lights.
