Thread: Turn your Nuvi 510 into a Zumo 220

Thanks for your answer, I searched the whole forum before posting this question and tried several ways to enter the pre boot mode. The only way that there's something happning is by holding the upperleftcorner and after a while I come in the calibration screen "press the white dot" and after a few seconds it's going to boot further and comes into my "problem screen" loader loading...

Ok, I managed to do an update, I read somewhere else on the forum that you have to start the updater before the calibration screen pops up...

Update 2: managed to install the firmware with the great cure tool and now it hangs only with the Garmin logo connected to the usb (it recognize the usb disk, yay!). I don't see the picture with the computer and when I disconnect it from the USB the Garmin turns off... what can it be?

Update 3: It works!! I installed the "normal" zumo220 update firmware after the cure and now everything is fine. Thanks to all the information on this forum!
