Starting RVing again; have GPS & backup camera questions?

[GlennB]

After several years of not camping/RVing due to health problems, I'm now ready to hit the road again. I plan to tow my 2004 Keystone Laredo 29' 5th-wheel.
Here's questions:
1. I have been unable to update the maps on my Garmin RV760 GPS. My computer just doesn't seem to recognize that I have it connected. U'm using a USB cable that I had labled Garmin RV760. I remember I always had problems updating the maps. I'm thinking of getting a newer model, one that you can update via wi-fi. Am thinking that the RV770 looks good.
One question is: Can you select 3 or 4 items to show at all times? I like "Miles to next waypoint", Miles to destination", and "Elevation". The screenshots I've seen don't show that.
I have a non-Garmin camera on real license plate that connects to the rear of the RV760. It appears to me that I would have to purchase a Garmin BC30 wireless camera to replace my hard-wired camera? Correct?
Also, several years ago I paid a guy to install a no-name wireless backup camera on the rear of my trailer to be displayed on my RV760. It never worked. All I saw was static and occasionally a very brief glimpse of behind the trailer.
Any suggestions?

If you can't get your Garmin updated this would be a great time to dump it and move to using Google Maps or WAZE (or both). They are more accurate, give real time traffic information (unless you choose not to use the cellular data) and it's FREE!

FYI - I have a Garmin RV660LMT with a Garmin BC30 camera mounted in my ultra light TT (fiberglass shell on aluminum frame). Garmin says that setup is good for up to 45 ft. separation between camera transmitter and GPS. My RV660 picks up the BC30 signal atleast 200 ft away when parked at the CG.

To fix your map download problem on your RV760, I recommend you download and install a fresh copy of Garmin Express on your PC. That installation should correct any bad connectivity settings on your PC.

Garmin RV760 requires a BC20 camera (now obsolete) NOT the newer BC30 model. The wireless receiver on the BC20 model is located in the special mounting plate on the back of the RV760 GPS. The receiver for the BC30 is located in the power cable. Without that special mounting plate receiver (which is part of the BC20 kit), I doubt that a BC30 camera will work with your RV760. This LINK may help explain the differences between Garmin cameras.

I'd add the recommendation that you completely uninstall Garmin Express before you install the newly downloaded copy.

Wireless backup cameras have limited distances that they will cover. Many operate on the same frequency that many other household items use. Therefore the interference is huge. Whatever system you choose don't go cheap. There is a very good business in Baton rouge that offers a variety of cameras. I forget the name but Google backup cameras and Baton Rouge and you will 0it.

The USB cable you use doesn't make any difference as long as it has the proper USB connector type on the GPS end. I have NO problems updating our RV760 - and do it as often as updates are available. What kind of computer are you using and what version of the operating system and Garmin Express?

As for rear monitor cameras, I prefer a separate system for that so that the GPS is viewable at all times.
