What is the actual resolution of your device?

The resolution now is x-480 y-234

Beefje, check out data.zip. Best for safety copy it to your PC, next unzip, then look in the folder ui_igo8 or ui_igo8_da (dependinding on your igo build). In that folder should be a folder called 480_234.
When that folder is there, your resolution is supported. When so, delete the save folder (it will be replaced when starting again). Then start up and do the settings over again. The correct resolution should be detected during start up.

This has your resolution http://www.navitotal.com/forums/showthread.php?1837-Working-iGO-8.3-from-my-device

Nabi I have don as you wrote and everything was but when I came on the place of destination and switch of the engine and when I turned it back on and go to the gps its the same as before again to big screen, how do I solve this?

Are you 100% sure the resolution is 480*234? No, 200% sure.
Did you get the device together with iGO8? Can you tell what build (menu-help-about)

Delete these lines

resolution_dir="320_240"
vga=0

and

screen_x=320
screen_y=240


Delete the save folder again and start up.

All the Xtron 7" 1dins I could find are as follows:
D710= 800x480
D709 and D708 = 400x234

If any of these are correct for your unit, you are not running iGO with the correct resolution, and the distortion/mis-sizing you describe will result.

Oke nabi I have delete the lines and will try tomorrow, and yurbuh Mine device isn't not D710 or D 709 its a lookalike those are the newest models

I have deleted those lines and tomorrow I going to try again , what those 3 devise consurn is te followed they are probely the latest device's

Nabi I have just trying it out and as long I don't switch off everything works ,from the moment I switch back on the radio and go to gps its again a screen with to high resolution ,no I don't now what to do to solve this problem

Nabi I have just try it out and as long I do not turn off the radio everything is oke, wen I switch of and back on the radio resolution is again to big,so how can I in the end solve this problem

First we must be very sure what resolution your device is. I mean VERY VERY sure.
Goto http://www.navitotal.com/forums/showthread.php?909-Double-din-2Din-GPS-How-to-install-thread, scroll down a bit and download a resolution tester. Test and report back.

I will not be here anymore till next sunday (12th), but one of the team members will certainly help you further.
