The main problem with using TYRE and the like is when it comes to uploading to your unit.
The unit detects that the route has been done on a different map data and asks if you want to recalculate ..
It then recalculates and gets you from A to B but it varies the route to suit its map/routing settings which is no good if you want to stick with the B road twisties..
If you choose not to recalculate then the route is just a mess of waypoints paths and dots..
When Simmo and Clive used to send me routes done in TYRE I could never get them to load properly .. I could sort the gist eventually but it was a mare.
Moral is, Make sure the map in your routing program is the same as the one in your unit that its registered with to minimize the gremlins.
Use Basecamp or Mapsource or even TYRE if it lets you install the same map to calculate your routes ( which I have never been able to do) Anything else and for me its just asking for trouble...
I think its a bit like Apple and Android, they dont want you using other peoples software if you get my drift..
Stick with mapsource Tim and plot your routes on your puter before you go... I also found basecamp over complicated so Im sticking with mapsource
which was made for garmins by garmin.. Your Routeapp and Tyre is a Tom Tom thing I think and as I said they dont like you going cross platforms....
Changing tac a minute my 660 has worked well since I had it apart from this Invalid Battery detected thing, Went to Kostas last night and it flashed up about a dozen times in the space of 5 miles
Done it from new but never this bad. Im in the process of contacting garmin and/ or sourcing a new battery.
Nothing like sat nav gremlins to spoil your day so I want to sort it before season starts proper..
If anyone has heard of this or has any info please shout up because I cant find any
