Bt-77 bluetooth gps review

The BT-77 bluetooth gps receiver is very popular, I would consider it one of the most popular gps receivers. This is because it has been sold under different names including itrex, avl and other names

The bt77 uses a nemerix chipset, it is a 16 channel GPS tracking up to 16 satellites. Once fully charged it can last up to 30 hours. The box contents include the gps receiver and battery, an ac charger , usb car charger , a usb cable  and a cd. It may also come with a dashboard mat to place the receiver on so t doesn’t slide around. Because it comes with a usb cable , it can also be charged from a pc.

The device itself measures 81mm by 44mm by 20 mm. It has 2 flashing lights, a blue and red one,  the red light flashes when it has locked on to enough satellites otherwise it is steady. The blue one has to do with Bluetooth functionality. Read more
