No, TomTom maps haven't improved much over the 18 months for rural ireland. They use TeleAtlas. Google also used Teleatals (for Ireland) until they booted them out during the summer. Since then Google have been very proactive in dealing with reported problems. I know because I have reported about 50 since June and they have fixed about 48 of them often within hours.
I reported lots more to TeleAtlas and despite assurances that they had fixed the Issue they never made the fix.
TomTom are very poor for rural Ireland.

I am involved in map corrections around Ireland & I can list hundreds of corrections I have got addressed. If you want to forward me anything in particular I'll get it looked at.
What map are you on at the moment.?
