Garmin GPSMAP 478 Repair Service

Description of some of the features and options

• Base Repair Charge
  There are two options here 1) Base Repair Charge - This is the charge that covers the base part of the repair, evaluating the unit, taking it a part and other activities to make the repairs below. 2) Request For Quote - Use this option if you really do not know what is needed, the repair is not in the list and/or the unit does not start up, if you choose this option do not choose any other repairs options below. This charge covers evaluating your unit to determine what is needed or what might be needed. After the evaluation you will be contacted with a quote for the repair, you can then either accept or reject the quote, if you reject the quote then we will ship the unit back and no further cost is required.
• LCD - Liquid Crystal Display
  • You are able to turn the unit on and off but either there is no display(white screen), the display is washed out in some or all places, or you can see a crack anywhere on the screen. For an example of a bad LCD click HERE.
• New Internal Backup Battery
  • The internal battery backup is used to save previous satellite data in volatile memory each time the unit is turned off. This helps decrease the TTFF, Time to first fix. The time it takes, after power-on, to accurately compute your position and time using at least 4 satellites. If you are in the same location, the satellites have not moved much and your internal backup battery is good then the lock will take place in about 1 second. If the backup battery is bad then the lock is likely to take more than a minute or never depending on your current signal strength and condition of the backup battery. If your internal backup battery has not been changed it should be replaced at the same time as another repair, even if it appears to be working as the typical battery life is typically three or four years.
• New Cells in Battery Pack
  • There are aftermarket battery packs out in the market but many of them either do not work or use substandard cells, we use new Samsung cells and because we reuse the original battery circuit within the pack it is guaranteed to work correctly.
• USB/XM Radio Port
  • This is a very common problem, during the automated manufacturing process Garmin did not use enough solder on this part and there is a lot of potential stress applied to this part. If the unit no longer communicates with your computer or XM radio when plugged in to the USB then the jack will be the problem
• RUSH!!!
  • Every effort will be made to send your GPS unit back out the same day as receiving it, these are top-priority upon receipt.
