This device will make a nose sometimes as you get closer to turn. Please keep in mind, that there is a few second delay between the device and instructions issued to the device by the satellite. Unfortunately, there a few seconds delay between the communication between the two devices and its relay to you, the driver. You will need to anticipate that delay, the screen is very helpful prior to turns or voice communication. It would be prudent to get use to the delay communications and use of good discretion as you drive. If you go past or make the wrong turn the device will re-calibrate but its also takes a few seconds to do so.
