Hi all I hope someone can help me I have michalin green guide on my garmin 3490 but am unable to see it on device to navigate to a poi but when satnav connected to PC I can find it in poi folder but I am sure it was not in custom poi folder before last update so I would like to convert the michalin gpi file back to csv to reinstall it but I am not having any luck, the michalin file is large 277 mb. Any help to either suggest what the problem is or how I can convert would be much appreciated. Thanks in advance Dell
