Hi all,

I would like thoughts on three units for comparison, I need to know based on the following factors which is likely to be a good solid purchase;
1. Ease of use - for going from map to menu and back and manually entering an address to navigate to.
2. Responsiveness of screen - the easier it responds the better when using it.
3. Accuracy -  navigation and timing need to be as accurate as possible.
4. Traffic - how far in advance will I know of delays and how well does the unit do at changing your route to a better one.
5. Refresh rate - I need the mapping to be as fluid as possible no jumpiness or lag in the update as driving.
6. Australia and NZ compatible - I need it to work NZ wide and throughout Brisbane, Sunshine Coast, Gold Coast and maybe other areas of Queensland.

Traffic is a nice feature that if it works I would find useful, nothing worse than travelling what was the best route only to come across road works or an accident and be held up, but navigation is more important as that is the basis of the device.  Also accurate current speed limits, on this though, how does this adapt to the changing speed limits in Wellington.

I have been looking at the units available at Harvey Norman Garmin Nuvi 55LM although this unit does not have traffic the Garmin Nuvi 55LMT does, the Tomtom Via225, this does not have traffic either, and the Tomtom Go50 with has traffic via smartphone.  I don't plan on using mobile data in Australia at this stage.

Basically I want a 5inch minimum screen at a good price.  I had a go with a couple of Garmin's and Tomtom's at DSE as they have them going there as opposed to not going at Harvey Norman, I was hoping to find one which had the best sensitivity / responsiveness of the screen but it kept changing one minute the Tomtom was better next it was the Garmin, so came away not to decided on that side, but as for the menu option they had a Tomtom Go600 which was nice to use for the menu side... but out of my price range really, I don't want to spend the earth on a GPS, it will be used for our Holiday to Australia and travelling to new places around NZ to ensure we can get to where we are going without getting too lost, not that this does not add to the adventure, but it can be frustrating and add to the anxiety in the car when all the family are in there and we may have been on the road for few hours already.  Also I am likely to use it as an always up to date map for going into Wellignton City on my own so I don't get lost.  I don't need it for my every day commute.

Last but not least, what ever happened to Navman, other than what I read about the company I have noticed they have dropped lower on the market.
