Garmin 660 & 770
What does the standard power cable for these units look like? The BC-30 Backup Camera has a replacement power cable that has an in-line receiver for the camera module that also includes a traffic receiver. I've decided not to buy the camera for this reason as the receiver is only inches for the back of the GPS unit and would lay on your dashboard. Now I'm wondering if the GPS itself has a similar traffic receiver.
I'm planning on using the GPS in my auto as well as the RV. I don't need the camera for the Vegas, obviously, and I can live without it in the car. But if the GPS has a similar traffic brick, I will have to look at other GPS units.
