In order to see map on my vehicle I am currently using Garmin device and I found it very amazing. It has all the latest route and roads blocks in the proper position. But, in order to get more maps and advanced features I have to use Garmin Map Updater and update this device. Can anyone tell me how to download Garmin updater as I don’t have any idea how to do that? Please share your ideas with me so that I can able to update my device and roam tension free.
