The unit has not work for more than one day Freezes all the time screen will not refresh. I have missed that many turns since I have had it. I can only use it as a camera, If I dare try to use the navigation the screen freezes

The camera of the head unit failed after nearly two years.
I contacted Navman (Hazel) via email and followed her recommended and suggested fixes. Although Hazel was very friendly and helpful, the fixes were not successful.
I returned the head unit from Canberra to Sydney on a Thursday. A new head unit arrived the following Tuesday. Can't ask for better service than that.
Congratulations NAVMAN.

Heap of crap, (keeps freezing), buy another brand, save the frustration. Bought it 2mths ago for a trip, over the 6000kms covered it worked for maybe 1500kms. Updated it tried again back in Brisbane froze 10 times over 45min journey. I found it outright dangerous, as I was focused on the frozen screen instead of the road.

Have had this unit for 1year now been sent to Navman three tines now 1st time camera stopped working and Navman replaced unit 2nd time screen freezing when on a route but doesn't freeze when just normal sent back Navman sent back saying they updated software next time after same thing sent back to me saying nothing wrong but away this time when on set route unit freezes for up to 5 minutes then catches up then freezes again and unit gets very hot
Will try sending back again or will just trash

June 27th 2022 Update: Update on review

Navman has done the right thing and after testing my unit have agreed that there is an internal fault have replaced it with a new one even sending me a pre paid aust post return lable
Well done navman.

I found that it would not turn on when starting our journey. I would do it manualy sometimes it would stay on, sometimes not . I found myself taking it out of the vehicle and charging it in the home still finding it would do the same. This is continual charge all the way through !

The first one died and JB replaces it very quickly (suggests it’s commonplace). But, it’s rubbish nevertheless. Often locks up showing the navman screen. Tells you about cameras on roads you’re not on!? Gets the distance to objects completely wrong, like it doesn’t know what speed you’re doing. Just yesterday it told me about a camera 20Metres away whilst I was doing 100kmh and the actual camera was 150m behind!? It won’t allow you to turn off the stupid lane deviation/ collision warning “feature” off!? This gps is a total pile of junk!
Btw the 4WD maps are almost non-existent and rubbish when they do exist.

I purchased this unit in January 2018 for a specific task during a trip in central Australia in August 2018. The unit work flawlessly whilst on nice smooth road surfaces for the first 3 months or so & then the bugs started to show up, unit failed to switch on even with a full battery, sometimes it would freeze just after start up.
The journey up through SA & in to NT was plagued with issues with the GPS device, several times hard re-sets had to be done to get the unit to power up & work accordingly.
Not overly impressed by this unit, could do with some further development especially in the are of off road stability.
Looks like I maybe returning it for a more substantial device.

I bought it several months ago but rarely use it as it often not reliable and unresponsive than our google maps on the phones. There are several issues some which were outlined on other reviews. The one most annoying is that if you turn it on without starting the engine. It starts. If you then switch on the engine it just shuts off or freezes, there is nothing you can do to power it up or reset it. You must have to unplug it so it completely runs out of battery thereby unfreezes itself.......
Screen is also extremely hard to see under daylight.
Video or photo taken can’t be played back. It keep saying no data.
I really regret buying it now as it’s is such painful experience using it.
