Evermore is a Taiwaneze manufacturer that produces quality GPS products for all categories of users. The BT-R900 is their top of the range product for BT GPS devices, using the SiRF III chipset. The device's performance is sufficient for everyday use. Despite the fact that it didn't quite reach the performance of the Globalsat BT-338 (also powered by the SiRF III chipset), which had higher number of satellites in use and better average signal levels, you won't face any problems in everyday use. If we need to complain about something, it is about the TTFF (Time to First Fix) performance, which was at best, 85 seconds. We expected times to be significantly lower than this. The lack of an external antenna connection, which would be desirable, is typical for this category of device, but there should be no problems here since the device displayed good reception.

The retail price (~US$120.00) puts the device in the Globalsat BT-338 category. Both devices are very similar in dimensions and specifications, but there were some differences in real life performance.

The Positive

• SiRF III chipset provides good performance
• Supports WAAS/Egnos
• Small dimensions
• Good retail package
• Includes mini-USB port for charging
• CD with manual and testing software included
• Car charger is included
• Device turns off after 10mins of inactivity

The Negative

• Not as good performance as BT-338
• Doesn't support any automatic power on mode
