I also Have a 760 LMT and BC-20 camera. The GPS works well. Have you tried attaching mount to top of dash vs. windshield?
There is a smooth circular disc that you can use to attach the suction mount toy. With the disc mounting to the top of the dash is easy.
I also have the BC-20 wireless. I get sporadic reception from the rear of my fiver. Camera is mounted to my ladder.
The big gotcha is the camera is weatherproof but the connections are not!
I have solved this issue by using a
1 1/2 PVC pipe as a junction box to keep all the connections out of the weather.
My next step is to move the transmitter closer to the front of the fiver. Currently it is also at the rear attached to the top of the ladder.
I received notice that my 50' extension cable has been shipped.
Once I attach the extension cable, I am confident/hopeful that I will get decent reception between the camera and GPS monitor.
When camera and monitor are working it's nice to have the large 7" monitor work as a GPS and backup camera viewing screen.
Currently the reception goes in and out meaning I have reception for a few minutes or seconds and then I don't!
I plan to post pictures of the entire set up once I resolve the reception issue. Keeping my fingers crossed.
