Sony NAV-U PCB & Chipset

The NAV-U GPS has a very exciting chipset, and here I have removed the metal shielding to see which chips are used.

This side of the board contains the GPS radio circuitry. The NV-U93T and NV-U83 also have a wireless communication feature through FHSS modulated Bluetooth Version 2.0. The power output is +4 dB/m over a range of 10 m, and the frequency band is 2.4 GHz.

Here you can see, all the sockets are on one side of the board. The jack socket is for the TMC aerial, and there is no audio output socket on this unit.

With recent advancements in microelectronic technology, one of the best mapping systems for mobile phones is Google Maps, which you can get on Android based Samsung mobile phones. This technology is likely to overtake all GPS products in the future. If you are planning to buy a new GPS hand-held then Google Maps is a serious contender worth considering.

Here you can see the main processor and the built-in 2 GB flash memory.

This is the PXA270C5 microprocessor, which runs at 300 MHz clock frequency.
