The TomTom is a reliable brand of GPS navigation. The TomTom 630 and 730 models are two of their elite Go Series, each offering unique features and functions. One of the key differences between 630 and 730 is that 630 is a cheaper model. However, the 730 models are missing some significant attributes.
These include map editing and map sharing, which is included in the 630 models. This feature allows users to make map corrections and share them with others. On the other hand, TomTom 730 has lane guidance, traffic information, map updates, route optimization, and voice activities navigation. The TomTom 630 model does not feature route optimization. However, it does turn text to speech.
