TomTom GO 620 software improvements
1. The warning sounds for over speed limit and speed camera warnings are too similar and you don't have any options to change it. On the previous generation models, you have the choice of many sounds and the number of chimes so you can tell clearly what the warning is about.
2. The colours schemes for the maps are very gloomy and boring. With the much better quality lcd compared to the previous generations, you should be able to put on some better colours!
3. It is nice the Go 620 can remember your routines and anticipate where you want to go on a certain day of the week. Say on Monday, I would normally go to A, so when I start my car, the Tomtom would ask me "Are you going to A?". However, if this Monday I need to go to B instead and enter the destination B, the Tomtom will start guiding me to B. But during the trip, it will still ask me now and then "Are you going to A?".
4. Sometimes the voice command menu comes on and asks for a voice command from me, but I haven't said anything (I was only listening to the radio at the time, certainly the radio didn't say "Hello Tomtom"!)
These are the few annoyances I experienced with the 620. I hope your software guys may be able to do something about it to give the 620 a even better user experience!
