Globalsat's BT-359S is the next generation design for BT GPS products. The new design from Globalsat is very good and very appealing visually. The device we tested was lighter than the BT-338.

In its performance and in comparison to the BT-338, the BT-359S was not that far behind, remembering that both are powered by the famous SiRF III chip. There are some differences as our tests showed, with the most obvious being the higher TTFF times. However, we believe that this and other areas will be improved before the device becomes available.

Overall, we were satisfied with Globalsat's BT-359S and its new design. The retail price is not yet known but should be at around the same range as the BT-338. With the fine tuning that has been promised, the BT-359S could soon become the next champion of the BT GPS arena.
