Updated recently to United_Kingdom_and_Republic_of_Ireland_1105_11752.
Used it last week for a long trip not being to the destination previously.
Noticed the map following my position being slow and I missed turnings because of that, and then while rerouting a new route. TT shut down and rebooted, so as not take another wrong turn and had to stop waiting for it sort itself out.
Not sure if its the map as all the previous versions never had a problem or its my TT.
So think its time to boot TT for a Smart phone or newer model as I use TT overseas saving roaming charges.
Unless someone can convince me not to.
