The XL340S Navigation Device does NOT accurately verbally recognize ZEROs in Freeway numbers. In Southern California it is unable to recognize the 805 Freeway, the 405 Freeway, the 605 Freeway or the 101 Freeway. It says west in place for the Zero. It is confusing in San Diego where the 8 Freeway and the 5 Freeways cross.
The TOMTOM Company claims to be unaware of the problem with the XL340S Navigation Device. For no charge they took back and replaced my XL340S Navigation Device after 15 hours of advising me to reload Maps and Voices to no effect. The new unit had the same problem of not recognizing Zeros in Freeway numbers. I spent ten more hours on the phone with their help line trying everything again on the replacement XL340S Navigation Device.
It is obvious that the XL340S Navigation Device has faulty software that TOMTOM refuses to fix.
Don't buy a XL340S Navigation Device if you plan to drive on Freeways. Get a unit from a different company.
