Garmin SatNav Really Disappointing

[TomGould1313]

Hi,

I have just installed Garmin sat Nav on My 8GB last week.
at first i thought it was good but now i have put it to the test i am very disappointed.

Basically the problems i am experiencing are:

1 - It gets confused driving down the motorway an is "unable to calculate route" after it has already done it sucessfuly
2 - around town where i live the routing is useless, it sends me all over the place and sometimes the wrong way up 1 way streets.
3 - the speed camera detection doesnt work even though it's turned on
4 - the lag between getting to a turn and it telling me to turn. up to 30 secs after the turn

Has anyone else had any of these issues or is it just me ?
