How do i enter the address in my address book so that my TomTom can recognise it??

Great app works like a TomTom device except with iPhone control which I like it better.
NB: the iPhone GPS will not work under a building.

I have used both and I thought I would add my thoughts.

Sygic lets you plan multiple destinations trips and I think has slightly cleaner maps.

Tomtom has better voice instructions and you can use contact addresses.

I have the TomTom Australia. (cost less than NZ). VERY accurate with the latest maps!! when no GPS signal, just needs to hold up on dashboard.

I gotta say i am a little ticked off with this APP…everything works great but the maps are about a year and a half out of date…loads of roadworks were done in my area of Auckland well over a year ago now and all are still shown in there old states.

Still a useful app but to release this with out of date maps and still charge over $100 is pretty low…we better get free map upgrades!

I use the DLO Vent as well and no problems with GPS lock. Occassional lose position but no very often. Have you tried a reset and or restore??
Another thing is to get a good fix 1st-ie stand in one place for a while.
But if your main map app is ok then its prob not this issue

@ iPhonewzealand we use the DLO VentMount which is available from MagnumMac stores

No the Sygic Maps, but same princpal
