Although I like the Tomtom a bit it has some serious drawbacks

1) the exits are listed as numbers rather than names - not good for California where almost nothing is labeled as a number and useless if the signal is lost to know what exit you are looking for

2) I can't find any decent way of getting support in the US - even to ask simple questions - like do they plan an update of above?

3) maps are quite old and have led me astray a few times in N Calif b/c of lack of current map (which Magellan had correct - but I didn't like the magellan for other reasons)
