Hi all - I am now realizing that I never installed a map set that I purchased a year ago. When I now click the download link, I believe it sends me to the most current map version - not the one I purchased a year ago. For example, I purchased the following map package ending in MAP24.1. However, when I click the download links, the map ends in MAP26, not MAP24.1. I've followed the instructions on updating the charts on the micro SD card and have input the unlock codes. My TZT2 says codes have been accepted, but the MAP26 chart is still locked. Is there a way to find the old MAP version so I can download it and unlock it? Would not be ideal if I now have to repurchase it again just so I can unlock the newer version. Thanks.
