Computer doesn't reognize nuvi 2797.

Hi @wabenoflyer ,

Use a strong light and a magnifying glass to visually inspect the device’s USB port for an obstruction which may prevent a good connection. Also check that all the pins are there and that they are straight and parallel with each other.

If the port appears to be blocked, try using a vacuum cleaner to suck out the debris. Do not use a metal pin or probe as you may damage the pins. If necessary use a sharpened wooden toothpick to clear any obstruction.

If the port enclosure seems clear try the following check to determine if the USB connector is loose from the systemboard.

Connect the USB cable into the device only. (leave the other end of the cable disconnected)

Firmly grasp the device one one hand and then grab the inserted molded plug of the cable with the other hand and very gently try to move it up and down and side to side to check if you can detect any movement in the USB connector.

If the connector appears to be loose (or even if it isn’t) the device will have to be opened and inspected as to what the problem may be.

Here’s a link to the ifixit Garmin Nuvi 2797LMT Motherboard Replacement guide.

It is useful as it shows how to open the device so access to the USB connector is possible.

In the image at Step.4 of the guide, the USB connector is seen (top left of systemboard).

As it is a SMD (surface mounted device) type of USB connector, you’ll need SMD soldering skill and tools to effect the repair or replacement (if the connector is faulty).

If it is just loose and you haven’t the tools etc, take the device (leave it disassembled - handle gently) to a reputable, professional electronics or mobile phone repair service and get them to solder the port back again.

If the port is faulty then search online for a compatible USB port
