[TG] [TG11] Rs 150 GPS pins

[Alby]

Hi I'm new to raymarine products was told it was the best so I bought some on the cheap because my pockets are limited especially if the wife is watching ,
I purchased two E90w MFD and was impressed but I'm now attaching a GPS 150 and can't get it to work not even the light on top it's connected via a 5 way connection point with a power line to it but no signal or light
I have checked all connections and the seem fine but I looked inside the socket on the rear of the GPS and it has 6 gold spots and only 4pins if looking at it as a horse shoe legs pointing to bottom it's the first two pins missing or are they ,any help would be appreciated before I send it back thanks Alby
