Hi I have a Garmin 650. I've searched the forums but have not found a thread for my question. I have the 2009 North American maps installed on the system memory. I've copied and I am running the gmapsupp.img for north america 2011-3 to my sd card on the device. I have them both the 2009 and 2011 maps checked under map info in the Garmin. Will this present a problem? Should I only have the 2011 map checked? Thanks
