Description of some of the features and options

• Base 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.
• Digitizer/Touchscreen
  • A new digitizer is needed if one or more of the following conditions are experienced; (1)the GPS does not register taps on the screen, (2)locations on the screen register erratically and/or sporadic taps, (3)location where you tap is registered somewhere else on the screen - for example 1/8 up from tapped area, (4)during the screen calibration either the GPS does not see your taps or never completes the calibration process, (6)if your have digitizer/top glass is cracked.
• 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 Battery
  • While the unit is plugged into the car/wall charger it charges but does not use the battery, if you need to use your unit while not plugged in and it does not last long enough then it will need a new battery. In some cases the unit will not start with a bad battery but more likely the cause is a bad USB jack.
• USB Charge 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 does not turn on, or you occasionally get a low battery message while the unit is plugged in or an indication that the power has been disconnected and the unit will turn off or if it no longer communicates with your computer 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.
