Questionable product
My SirenMarine was hooked up, but does not read any engine information. Only gives me location of the boat and the batteries that are plugged in. So far not worth the money. Not sure if the shop screwed up or it's the siren 3 machine that is not working correctly. Not getting answers from shop which says they aren't getting answers from Siren Marine. SirenMarine also does not give you Inst ructions on how to use the app or how to use anything. Tried looking online for instructions, but there wasn't none either. Only thing online is how to set it up, not how to use the app.
