Question about Garmin StreetPilot C330 GPS Receiver

1 Answer

Garmin StreetPilot 2720

It turns off and immediately restarts itself every minute or less. Doesn't matter if my car is idling or rolling or if I'm programming "Where To" instructions. I disassembled the GPS adapter plug, but saw nothing abnormal, and reassembled it securely. If you tell me to test the cigarette lighter, how do I do that? Thank you.

First check the socket a cigarette lighter! You could borrow one if you've lost yours because they are all the same size. If it works then read on.. Most cigarette lighter ADAPTERS I've seen have an LED on them to tell you it's making good contact. If it has got an LED but it's not illuminating then unscrew the black cap at the tip of the adapter and check the fuse. If the fuse is blown replace it with one of the same rating. If that was no help at all then try resetting the Garmin. Unclip the face place and press the reset button. Now try turning it on. Hopefully I have given you at least one thing new to try! :) Regards, SparkGap

Garmin 2720 lost sound

It sounds like the audio power amplifier is failing in the unit, it's kinda classic for an audio amplifier to fail when it gets hot, then work again when it cools down.

I'd suggest deleting the language you're using, then reload v7.2 firmware and the language. No reason why this should work, but it doesn't cost anything. If not you're looking at a $250 Garmin flat rate repair.

Garmin GPS 2720

Unfortunately, Fixya is not associated with Garmin. We can only answer device questions and can't speak for the company.

Unfortunately, the unit cannot be upgraded. Garmin provides both in and out of warranty repair service if the unit is having a problem. The 2720 sells for $49 on Amazon, so it probably is not worth your while to have fixed.

The 2720 is known to have issues unfortunately, it is pretty lowly rated on Amazon.

Hard reset

I was told that you turn off the unit, hold down the FIND key and turn it on while holding. Keep pressed for about 10sec. then release.

System missing

Well, for the 2730 which is basically the same, you turn off the unit, hold down the FIND key and turn it on. Hold for about 5 seconds and release. It should reset the unit.

Unlock Code

When updating the maps, you need to be registered with Garmin. All the numbers came with the unit. If you turn over your Garmin 2720, there will be a number flanked by "*". That is your unit ID. When you register, you must provide that ID. From the site, you can update your maps and you shouldn't need the 25digit key. It's programmed into your unit.

Restarting while in use

Mine just started doing the same thing. I took apart the speaker power cord, but don't see anything wrong with it. I thought I saw the unit turn off/on one time when I moved the cigarette plug back and forth, but as I said the wires are fine. I have the power cord apart right now and have 12 volts hooked up to the wires directly and the unit has been sitting here for 30 minutes without resetting.
