To be fair, it hasn't been updated since 2013.
And the map will be 12-24 months out of date at that point as well... ...though in reality, not many roads have been completed in that time frame, aside from new housing estates etc.
So whats wrong with it, just roads are out of date, or something else (that an update wont fix)? I always maintain that any factory fitted one is leagues ahead of any portable unit. Even the NCDC in Omegas is a very, very good unit compared to even modern portable units, apart from even the newest maps are now 10yrs our of date (and millennials will get hung up on lack of postcodes). NCDC isn't the easiest to use, mind, beyond the basic "take me to this address"
Been very happy with mine tbh, Mine is the fully built in Comand though.
I wanted to update mine for 3 main areas:
1, My Commute - I use satnav there and back to let me know if there are areas I need to avoid, It didnt know about a new major road into Crewe, which is often the best route in when its busy.
2, The Mersey Gateway - This is a new mersey crossing, Old Runcorn / Widnes bridge currently shut too, can be a bit awkward to navigate when it thinks your in the river!
3, There is a kind of Stockport 'relief road / bypass' that starts at Manchester Airport, lets you bypass a load of Motorway / traffic which is handy visiting family.
So the updates are going to prove valuable to me, The extra roundabouts / housing developments / poi's are all a bonus too, as it the updated gracenote db.
Ive the maps and instructions too now for when AA fancies a try at updating his.
