Looks like you somehow lost your Insane NavEngine. No problem we will get you all fixed up. We just need to have you reinstall Insane NavEngine.
To re-install Insane NavEngine:
1). When your JK1001 is fully booted up, click on the “six pack”, swipe to the right, then click on the settings icon. Scroll down and select “Security”. Check the box next to Unknown Sources to allow installation of apps from unknown sources. Click OK on the pop-up window.
2). Make sure your GPS card is in the GPS card slot. From the home menu, click on the file manager, select the GPS card (on the left), then go into the Insane NavEngine folder. In here, click on the iGO.apk. Scroll to the bottom and click on install.
