The cable with the kit is unwieldy.
You have to join the DB9 pin male and female together (format is the same as old serial port on a computer) but it doesn't come with nuts to make it secure. One end goes into the cigarette lighter, another into the scanner and the puck goes on your dashboard.
The puck has a red led, it blinks but nothing tells you with the kit what the led indicates.
This kit probably works with other scanners utilizing the DB9 connector. It might be good for the manufacturer but its a pain for the end user with a 436.
