Abnormal Powerdown Error Code

This is the error code I get when checking the diagnostics. It is slow to receive satellites and wont stay on unless plugged in. Ive been charging it on my usb for 7hrs and it has been to no avail. It seems others have this issue so you'd figure Garmin would provide some insight.

Your battery is dead, which is causing the problem with "slow to receive satellites". Normally when you turn off the unit it will remember the last location and time, then the next time you start the unit it already has the time and current location to acquire satellites, but with a dead battery it has to start from scratch. Check the screen and see if it says "Locating Satellites" or "Acquiring Satellites". Locating satellites will take longer. Replace the battery and your problems should go away.

DTC P0423 diagnostic code

Try replacing your air filter, then reset the code and then if the same error pops up then you can replace the sensors one at a time. Chances are the sensors are the same component in 2 different locations (ie they are interchangeable). Replace one of them, reset the code, if the error comes back then replace the remaining unit with the originally replaced unit.

Correcting GPS Satellite Reception Problems for some Receivers

There is a way to "persuade" many GPS units to use a specified communications port and baud rate for receiving the satellite signals. You need to have a little programming knowledge to do this. This may not be the problem with your unit, but it works on some receivers.

I cannot tell you all the exact procedures for doing so for each individual GPS receiver, but you may be able to do it yourself if you are bold enough, or have a friend who is experienced in basic programming. Make sure you backup and rename any files being modified, as improper code might put your unit to sleep...maybe forever.

All GPS receivers have a "setup" or "configuration" or "sys" file in the unit's main memory software that tells it how to startup and load all the various configurations...just like a Windows PC.

In one of the files will probably be a few lines of code as follows:


Your unit may have something similar to the above code. Find out what your communications Port is, and the Baud rate the modem is running, and that should force the GPS to run on those defaults. Some units will run ok on "auto" setting for the port. If you're game, it's worth a try.

One other little tidbit of programming info:

Something that has always annoyed me is the really slow simulation speed when you're trying to run through your route. Some units will allow a faster than 1X (real time) speed drive-through. Real time is sooooo slow. Look at this code:


Now look at this:


Which one would you rather put up with? The above information may not be feasible for everyone, but it's worth attempting if you want to try. Just be aware that it may VOID your warranty, if you're within that period.

These are just some suggestions to try. Maybe you can use them. If you do try, let me know how it works out. Thanks.

Regards, Bill

Intellinav.exe application error

The error 0xC0000005 is generated by an illegal "memory access violation". This can be caused by anything from faulty RAM, an incorrect/corrupt device driver, poorly written/updated software and more commonly under Windows XP Service pack 2, malware/adware installations.

Usually you get this error message when performing a specific task, and if that happens you need to check the corresponding 3rd party's website/support department to see if they are aware of the problem

..a while back symantec Antivirus caused the 0xC0000005 error with an additional message about a file called SAVRT.SYS . A simple software update to the Symantec Antivirus cured the problem.
So what can you do...? well below are a couple of suggestions:

0xC0000005 - Resolution Suggestion One:
In many cases this error has been generated by faulty RAM memory. So if you have just upgraded your computer with some new memory and you started getting this error then I would remove them and see if the error goes away. If it does then send the memory back and get a refund!

0xC0000005 - Resolution Suggestion Two:
In Windows XP Service Pack 2 Microsoft introduced Data execution prevention (DEP), a set of hardware and software technologies that perform additional checks on memory to help protect against malicious code exploits. In Windows XP SP2, DEP is enforced by both hardware and software.

Some software/application behaviors are incompatible with DEP - data execution prevention. Applications which perform dynamic code generation
(such as Just-In-Time code generation) and that do not explicitly mark generated code with Execute permission might have compatibility issues with data execution prevention. Applications which are not built with Safe SEH must have their exception handlers located in executable memory regions.

Applications that attempt to violate DEP will receive an exception with status code STATUS_ACCESS_VIOLATION (0xC0000005).

If an application requires executable memory, it must explicitly set this attribute on the appropriate memory by specifying PAGE_EXECUTE, PAGE_EXECUTE_READ, PAGE_EXECUTE_READWRITE or PAGE_EXECUTE_WRITECOPY in the memory protection argument of the Virtual* memory allocation functions.

If you are having issues with 0xC0000005 errors in DEP and a particular piece of software is causing the offense, contact the vendor for a resolution...

Note: It is possible to "Turn Off" DEP in the boot.ini file but this really would be a last step!

This option is only available on 32-bit versions of Windows when running on processors supporting no-execute protection. It enables no-execute protection (also known as Data Execution Protection - DEP), which results in the Memory Manager marking pages containing data as no-execute so that they cannot be executed as code. This can be useful for preventing malicious code from exploiting buffer overflow bugs with unexpected program input in order to execute arbitrary code. No-execute protection is always enabled on 64-bit versions of Windows on processors that support no-execute protection.

There are several options you can specify with this switch:

/NOEXECUTE=OPTIN Enables DEP for core system images and those specified in the DEP configuration dialog.

/NOEXECUTE=OPTOUT Enables DEP for all images except those specified in the DEP configuration dialog.

/NOEXECUTE=ALWAYSON Enables DEP on all images.

/NOEXECUTE=ALWAYSOFF Disables DEP. (This setting doesn't provide any DEP coverage for any part of the system, regardless of hardware DEP support. The processor doesn't run in Physical Address Extension (PAE) mode unless the /PAE option is present in the boot.ini file.)

0xC0000005 - Resolution Suggestion Three:
I have also seen this error in the gaming community when folks have updated drivers for their graphics card. If this happens just roll back your drivers.

0xC0000005 - Resolution Suggestion Four:
Microsoft Internet Explorer 6.0 stops responding when you try to open an HTML document or a Web page. Additionally, you receive the following error message:
Access Violation (0xC0000005 exception)


This problem may occur when you use Internet Explorer 6.0 to open an HTML document or a Web page that contains SPAN tags. If a SPAN tag is not closed correctly by using the </SPAN> tag, an access violation may occur.
WHY are you using IE6 still??? Upgrade to IE 7 today!

...and that should have now resolved the 0xC0000005 error for you!

Please rate this fixya

Charging battery unit turns off as soon as I shut down car and takes a very long time to find sateilites

I have the same issue. I did a diagnostics and found an error code that says "Abnormal Powerdown". Im trying to charge it via my USB right now, but it hasnt held a charge and its been charging since 4pm (7hrs). Im having the same symptoms as you, and am told that when the battery is dead, other things dont work, even when plugged in. Its worth a shot. If not, you can get a new c330 for 120 on the net.

Compass calibration

Hello. First day I use this device, and have found this tips for compass calibration (as I understand, compass calibration depend on satellite signals - so before compass calibration it's better to get good signals from satellites):
- keep device at horizontal plane (as from message "hold level");
- turn it slow, but not too very slow.
It's better don't turn device, but get device at hands, and turn around himself with it with constant slow speed, and keep horizontal level of device - by this way I have a more accurate calibration, than turn just in hands or on the table.
I hope this will help.

Coordintates seem to ALWAYS be off by 20-50 feet

How are you determining your error? If you are comparing your position to a map and you are getting error consistently, it could be that your map datum does not match the datum set in the GPS. Without WAAS turned on, your error should be @15'. With WAAS on it should be @ 6 to 9'. If you are using the Sattelite screen to determine your error, remember that is just estimated error. Higher estimated errors can be caused by satellites that are blocked or not visible to the GPS, or poor satellite geometry. It is normal for example, to have more error in high northern or southern latitudes due to less satellites being visible. With good reception you should be able to see 8 to 12 satellites on your satellite page. Signal strength is also important, You can have a lot of visible satellites but if the signal is weak your error wil increase. The signal can be weakened by heavy tree cover or high objects such as buildings or mountains. Such interference is called signal path error. Another form of signal path error is when the signal gets reflected off something before it gets to your GPS. For example; you're in a canyon and satellite 1 is to the east of you. The eastern rim of the canyon blocks the signal from satellite 1, however the signal bounces off the western rim and your GPS then picks it up. Because it took longer to get to your GPS, the GPS thinks that the satellite is farther away than it really is, causing a postion error. (This would not show up on your estimated position error shown on the satellite page because the GPS does not know this is happening.)

When WAAS is turned on it takes a channel that would normally be dedicated to a GPS satellite. It's possible that turning off WAAS helped you because having an extra GPS satellite improved your geometry which improved your accuracy more than the corrections WAAS is designed to make. The next time your error seems high, check how many satellites are being tracked and how strong the signal is.
