Question:
The blue light won’t come on when connected so I can’t connect to Bluetooth. What could be the reason why?

We do know of a few vehicles like the 2015 and newer Ford F-150's that have issues sending power to the auxiliary line on the 7-way which powers the Curt Echo # C51180, as they are required to put the truck into a tow/haul mode before it sends power to the 7-way. Otherwise I would start by checking with your vehicle manufacturer to determine if you have a similar issue. Next you will want to check your owners manual to determine what fuses/relays there are for your 7-way as it could have simply had a damaged fuse.
If you can provide me more information on your vehicle I can check and see if we have any known issues for that vehicle.
