Product History

The MileageMarker system is the brainchild of Carl Bright. He conceived the idea during the development of another GPS based device. Carl constructed a prototype of the device and installed the unit in his personal vehicle. Over a period of three months, he subjected the prototype to rigorous testing and software adjustments to perfect the operation of the product. When the prototype was operating as designed, he built twenty (20) pre-production units using production PC Boards and assembling them by hand. These units were then subjected to more field-testing and the units worked flawlessly. Full production began just before Christmas in 2006.

A provisional patent application was filed and registered by the U.S. Patent office giving MileageMarker LLC the right to label this device as "Patent Pending."

In our limited experience of introducing this product we have encountered some questions and we have documented some of these with the correct answers in this section to help you, as they will inevitably be asked again.

Some of these questions were written in anticipation and not taken from real conversations.

1. What happens if I leave the MileageMarker on when I park my car at the airport and go on a weeklong trip, will it run my battery down?

Answer: Yes. The mileage marker is designed for constant use. If left in a vehicle over an extended period of time it will run your battery down, you will not be able to start your car.

2. What if I forget to power it down when I make a personal trip, can I edit the log later?

Answer: Yes, the data is stored by day, date, and time. You can easily go into the file and remove any unwanted lines of data.

3. Will my miles be logged while I am in an underground garage?

Answer: No, the unit must be able to receive data directly from the orbiting satellites. If you are in a parking garage, the Mileage Marker cannot see them and will not be able to keep track of the distance traveled. You will be able to see this when the REC light goes off. The distance in a parking garage is typically only 1/10,000^th of the distance one travels for in business. Don’t sweat the small stuff; you are not losing much at all.

4. Can I be tracked by someone without my knowledge?

Answer: The MileageMarker is a passive device. It does not contain a transmitter; therefore no data can be transmitted from the device externally or surreptitiously. All data is stored in the SD data card. If you do not want to have travel data stored, remove the card, or pull the power plug.

5. What if I get the MileageMarker wet?

Answer: If the MileageMarker is subjected to light rain, wipe the case dry with a clean cloth. If the unit is accidentally submerged while out of the vehicle, DO NOT connect power to the Mileage Marker. Remove the SD card. Most of them are watertight and will survive a brief dunking. Dry the card off and put into a warm place overnight. Any water within the SD card will evaporate. Remove the two screws that hold the mileage marker together and then remove the PC board within. Rinse the Mileage Marker board under clean running water and shake the PC board dry. Further dry the PC board using a hair dryer and let set overnight in a warm dry place. In the morning, reassemble the Mileage Marker and insert the SD card. The unit should work normally without any damage. If the unit is powered up while wet, damage and corrosion may occur.

If the unit fails to operate, call the Mileage Marker Service line. The unit may be repairable for a minimum fee.

6. Can I use a larger capacity SD Memory Card?

Answer: You can use any SD card made as long as it is greater than 32MB. If the SD card is smaller than 64MB, you may need for format the SD card first. This is because the Mileage Marker requires the disk format to be specific. The only requirement of the SD cards is that the sector size be 512 bytes. You can use an SD card that is up to 4GB in size. NOTE: MB = Mega Byte, GB = Giga Byte

7. Why does the REC light blink occasionally?

Answer: The MileageMarker writes the accumulated mileage data to the SD Memory Card every 30 seconds. Each time the data is written into memory the REC LED briefly blinks. This visual indicator assures the user that his or her mileage is being recorded and that this trip is being recorded as a business trip.

8. Why does the REC light go dark when I am sitting at a stoplight?

Answer: When the vehicle is traveling slower than 10 MPH, the Mileage Marker does not record your movement. This is also a good indicator that the unit is fully operational.

9. Why does the GPS light go dark when I pull into an underground parking garage?

Answer: When the Mileage Marker does not receive enough satellite signals to make an accurate movement calculation, the GPS light will go off to show the user that the unit does not have enough GPS signal. Driving into an underground parking garage blocks all satellite signals.

10. Can I use the MileageMarker in a light aircraft?

Answer: Yes. The Mileage Marker can accurately keep track of the distance traveled in a light aircraft. The upper limit of the Mileage Marker speed tracking is 250 MPH. Most prop, LSA and experimental aircraft operate below this speed limitation.

11. Can I use the MileageMarker on a motorcycle?

Answer: Yes (just make sure that the unit is securely fastened down)

12. Can I use the MileageMarker on a boat?

Answer: Yes

13. How accurate is the accumulated mileage?

Answer: More accurate than your odometer. The Mileage Marker uses the GPS satellite system to keep up to the second speed and distance of your vehicle. Most OEM speedometers can be off as much as 1%. Add to that fact that changing the tires or rims of a vehicle, can change the speedometer and odometer output. Even under or over inflated tires can change the speedometer and odometer readings. Over all, the MileageMarker^TM will be more accurate than the vehicle’s speedometer and odometer.

14. My car’s internal temperature gets pretty hot during the summer. Will the heat affect the MileageMarker?

Answer: No.

15. What if I drop the unit accidentally?

Answer: Plug it in and see if it works. If not, call the Mileage Marker Service line. The unit may be repairable for a minimum fee. We keep spare cases and boards in stock.

16. I broke the SD card; can I get the data off of it?

Answer: Sometimes. If you can get to the pins on the card and place it into the SD to USB adapter, you can usually get the data off of it. If the break is through the center of the card, you are probably out of options.

Answer: Some vehicles only apply power to the cigarette lighter plug when the car is "on" or key on. Start you car. If the lights come on you know that was the problem. This is normal for some vehicles. The start up time for the Mileage Marker is typically less than 90 seconds and usually less than 30.

18. The Mileage Marker has a clear view of the sky and the GPS light still does not come on. It has been over 5 minutes. Why? The lights were on earlier?

Answer: There are 24 US GPS satellites and the receiver in the MileageMarker^TM has a 12 channels. Each of the satellites has a unique serial number that is known to the receiver in the MileageMarker^TM . Over time the satellites come in and out of view in the open sky. On very rare occasions, and only during the very first 24 hours of operation, the Mileage Marker receiver waits for a signal from a satellite that has passed out of view and holds that receiver channel open for approximately five (5) minutes looking for that satellite. If enough of these channels are "held" by the receiver it keeps the number of searching channels to a minimum and the GPS light is not illuminated. To fix this, reset the Mileage Marker by cycling power to the unit. It will reset the searching channels. Or be patient, in a couple of minutes, it will attach to new satellite signals. Over time, the GPS receiver in the Mileage Marker learns the whereabouts of all 24 satellites and this will not happen again.

When there is no SD card inserted, the PWR light will blink telling the user that the Mileage Marker does not see an inserted SD card or the SD card is incompatible.

If the SD card is not compatible with the Mileage Marker, the PWR light will blink. You can use any SD card made as long as it is greater than 32MB. If the SD card is smaller than 64MB, you may need to format the SD card first. This is because the Mileage Marker requires the disk format to be specific in only one area. Specifically, the only requirement of the SD cards is that the sector size be 512 bytes. You can use a SD card that is up to 4GB in size. If the SD card does not have 512 byte sectors, it can be formatted under windows XP to use 512 byte sectors. NOTE: MB = Mega Byte, GB = Giga Byte. Using the supplied SD card will guarantee compatibility. Buying an SD card that does not have 512 byte sectors is hard to do.

Answer: Place the SD card into the SD to USB adapter supplied with the Mileage Marker. Place the assembly into a Windows XP machine and wait for XP to recognize it as a new drive. After that open a command box or from the run line and type…

FORMAT E: /FS:FAT /V:MMARKER /A:512 /X

Replace the E: with the actual drive letter of the SD card. After this is done, your SD card will be formatted to FAT16 with 512 byte sectors.

The SD card slides into the slot. Pressing on the SD card latches it into place. The SD card should be almost flush with the case. If not, you have not pushed the SD card far enough into the case for it to latch. You will have a positive feel and click when it seats into the Mileage Marker. To remove it, press on the SD card and you will feel and hear the latch release the card and it will then protrude from the case about ¼ of an inch.
