Rearview or reversing camera and gps systems

Not sure if you've tried this already, but try Auto Barn - they have some reasonably priced systems that will suit a patrol. They can fit the system in the cavity above the main dash area. Camera faces down over the tow bar and also takes in a good area further out.

Just dont buy a wireless system or one with a rear vision mirror screen.

Been there done that binned both

Tyre pressure systems are different from cameras and you wont hardly need night vision as few people need to hitch up or travel in the dark.

Look at a website by SafetyDave seems people are happy with his.

I bought the parts and built my own.

HI Shelly
I installed the hema HN5i when it came out and fitted a Axis Ca402 camera 2 months ago , it works a treat. I put a seperate switch to power camera when not in reverse to see behind me and check campertralier when towing. Also fitted the new Sensatyre wtpms it can monitor your van or trailer as well, sensors fit inside tyres and are pressure operated, I have just been up to Karumba from the Sunshine coast and the whole system gave me peace of mind, hope this is of some help
regards Nobby.

I have had the Polaris system now for 3 years. It has performed faultlessly and was good value for money at the time. But if i was to buy today, I would be getting a unit from Brash Imports. Only ~$650 and has ALL the functions of the Polaris plus includes Ozi Explorer and uses Igo8 as the nav program (much better than Sygic on the Polaris).

Hi Shelly B

Just be careful that the one you get for the caravan is for rear view ie focused for long distance. Most are suitable for night vision. Reversing cameras are for short distance like you want for the rear of the Patrol. As Snoopyone says, don't get wireless for the caravan; we tried and it wasn't satisfactory for our caravan. If you are going to be monitoring traffic behind your caravan with a rear view camera have the camera to a separate screen (you can switch between the car and caravan cameras) to your GPS.

When we towed with the Patrol, my husband found it easier to open the rear doors of the Patrol and look than use the camera, or have me signalling him. We have an AT35 hitch and a fixed jack not a jockey wheel, so backing needs to be very precise. Would this be an option for you for hitching?

As said, tyre pressure monitoring is something different again and there are plenty of threads on these.

I have just bought my second setup for a friend. this setup is a 7" screen with windows ce, so is exploroz compliant. It has latest street nav software and wireless camera. It cost me $149 delivered. Evilbay but a Melbourne dealer so some of the money is spent in oz. great setup. easy fit...
