Car Gps

hi i have touch system car screen having the option of gps also. but how it will work ? should i have to insert the map cd or download map and save in sd card ?

where did you get that? and also mention the brand name of th device.

AFAIK mostly you need to update maps in it according to your location. if you got it from abroad then most probably you will not have Pakistan Maps in it.

and if you Purchased it from one of the local vendors then it seems that you might have them already (infact they(local vendors) are supposed to give them in it.)

but you always can update your device with the maps of your own choice if available. and if the device supports updating maps.

You need to get service provider. and you'll know all the details.

i am in dubai right now and nothing working here. so how i do update ?
