How to select the GPS Navigation system for car?
1) Frequent use: If use less, then go for inexpensive ones that can fit in car glove apartment, but are not user friendly. Also, check out budget as systems with maps/monitors are complicated and take time and money.
2) Layout of car: As GPS that come with monitor require some kind of installation, that may not be easy. Generally, installed on dashboard/pedestal from dashboard.
3) Features: Multiple ways to reach a destination, like address/location selected directly from map. Should also be able to give vocal (via head unit/radio), graphical directions (via a map and monitor wherein arrows indicate the present position).
4) Data displayed: Select one that offers data of your interest, like locations of airports, ATMs/banks, restaurants/hotels etc, which many systems include and the same to be updated easily.
5) Ensure that installation is done by authorised person as warranty may become invalid.
