My touch screen is not working properly. its co-ordinate position has been changed.

I just got a nice telescope and it came with a star chart. I think they use that as a guide

mos likely it is a cracked screen....even a minor crack not visible will cause it not to work........if the screen is fine then it might be loose ribbon connection or bad microprocessor or the phone is frozen/locked due to nmo more memory.....try to reset the phone.....to manufactures reset condition......if all else fails.....have the screen checked for cracked glass.....these screens have a liquid in between 2 pieces of glass and a grid template which act as a capacitor so that it responds to you touching certain co-ordinates on the screen....any cracks at all will render it useless and must be replaced, their is no way to fix the screen if it is cracked....good luck

you see the side panel control key then change it

the co ordinates of touch screen may have disturbed try, touching surrounding area of clear button or replace touch screen.

Unfortunately Garmin satnavs do not allow OS Grid References instead of Longitude and Latitude. However if you need to find the Longitude and Latitude of a point it can be done by going to http://www.gorissen.info/Pierre/maps/googleMapLocationv3.php Zoom in on the location you want and left click on it. The longitude and latitude will appear in a box to the right of the map. You need to set the co-ordinate system of the satnav to match the longitude and latitude format of the satnav. To do this touch Where to, Co-Ordinates, Format. Enter the co-ordinates and touch next. It's not an ideal solution but it might help you out if you're stuck.

Notice that when you pull up the MARKed coordinates the yellow cursor is on the N/S letter rather than the number. Since a number is impossible there it won't let you enter one.

Use the rocker to move to the popup screens directional arrows to move to the digit you want to change. This will be easiest with the the RIGHT arrow at first; once you see the cursor it will make sense. Note I am talking about the popup's RIGHT square and not the rocker's RIGHT direction.

Please come back and tell us if this fixed your problem, and rate our solution. Thanks.

It is probably giving co-ordinates in a different format. Go to setup and change the co-ordinates format to hddd.dddd and see if this solves your problem.

switch off the phone.. remove the batterya nd leave it for 1hour.. then again insert the battery and see what happens.. else do a firmware upgrade..

BNG stands for 'British National Grid'

1. Go to the Setup menu
2. Select Units
3. Change the Position Format to hddd°mm.mmm'
