You need a serial connectin on the back of your computer. you may not have one if its a new computer as its a little old school. You should be able to get a USB to Serial convert (make sure you get the right number of pins) and be good to go.

Sometimes this problem is caused by the power cord not being pushed fully into the back of the satnav even though it feels like it is. Pushing it in further usually solves the problem. If the power cord you're using is not a garmin this could also cause the problem.
First is to make sure you are using a Garmin miniUSB sometimes the units can be iffy about which cables will work. Also try other USB port on your PC the one your using may be dead. If this dosent work I would try someones else's PC to make sure its the unit and not your computer. If all this fails you my need to send it in for warranty.
There are a couple of tide software updates available on Garmin.com in the downloads and updates section. You will need to register your product and download. It took me a while fumbling around before I could find the updates. I got some "no updates are" available messages but there are, so keep looking. If you have a newer computer, you will need to purchase a serial to USB converter too. I had the same inaccurate tide message and the updates fixed my GPSmap 168. ps. you will need the unit ID #, and the Garmin instructions are incorrect. Go to menu 2x, Systm, then hit menu again, and pick "software version".
Are you using the garmin power cord or are you using an aftermarket cord? Some after market cords have usb plugs that although they plug right in to the power port on the unit, they tell the unit that you are updating the database. The unit displays only a picture of a computer connected to the unit and that's all it will do. Their is a way around this. Simply wait until the unit displays the about photo of the computer attached and then unplug the power cord from the unit. After the screen clears immediately replug in the power chord. This must be done quickly before anything appears on the screen. If you're too slow, simply repeat this step until you manage to replug the unit before anthing appears on the screen. Once plugged in as about the unit will operate normally on the external power source until you either turn it off or unplug it. Simple repeat above when ready to resume use.
The problem is very simple... The GPS unit perceives whatever you plug in depending on the power supply figure.
If you car charger is not giving enough power, then the GPS perceive the cable as being connected to a pc.... thus not charging. Check with an car electrician if you can raise the power supply on your car...
I had the same problem and contacted Garmin. This is being caused by a software issue that started when the government updated the software in their WAAS satellites. The Garmin website will give you instructions on how to correct this but I have listed them below:
Power on unit
Press enter to get past the I Agree screen
Now you should be on the satellite page, press the menu button one time
Highlight WAAS off and press enter
By doing this, the unit should not shut down.
I followed these instructions and my 168 Sounder is working fine.
Oh man.. I also bought the c330 on black friday... powers on and wont get past the blue street pilot screen--just shuts off! Will "work" when connected to the PC, but who's going to drive around with a computer?
