Satnav road screwups

[jhoneyball]

Am looking for specific examples where satnavs get it wrong. EG coming up M11 next to Cambridge, it takes you onto the A14 slip lane on the left, and then back onto the A14/M11 further up (on a Garmin with latest maps).

I'm not looking for short term issues -- road works, or other issues which are a week or two. I'm looking for long term errors -- postcode going to wrong place, road going somewhere it cant. Junction turn which is illegal. That sort of stuff.

I have satnavs. I have full lab GPS generator system. I'd like to try some errors you have seen and can describe. Email me jon at jonhoneyball dot com or post them on here if others are interested?

thanks for your help
