Before we delve into how to get upgrades for your Garmin GPS devices, understanding how the maps and navigational aids designed for Garmins work might be beneficial. So, in case you're not up to speed on the map software exclusive to Garmin GPS products, you might want to read Garmin MapSource Information for some very helpful general information about this software. A quick link in that series will also hook you up with details regarding GPS maps in general that you might not be aware of plus Topo maps from some of the most reputable third party providers. The Topo maps are phenomenal for the portable handheld Garmin GPS devices designed for outdoor enthusiasts, and, since we are talking about updates here, conditions in wilderness (trails, contours, elevations) areas that Topo maps predominantly cover don't change.
However, road maps, city guides, and Points of Interest (POIs) do frequently change from year to year for reasons ranging from failed businesses to the construction of brand new roads and interchanges, which is why upgrades are so important. Garmin recognizes the necessity to update and innovate its map products and, therefore, makes it relatively painless to acquire them on their website or with a CD-ROM. Unfortunately, the upgrades usually are not free. Glitches or defects discovered along the way in any of their models should, however; be fixed and/or upgraded when they occur. Should that be your problem, several different means for contacting Garmin customer service are detailed in the article referenced above, so just click on it.
In case you're wondering if Garmin will upgrade the actual GPS model you own to a newer version with more advanced technology, be assured that you're not alone. That is why they list this Frequently Asked Question (FAQ) on their website and then answer with an unequivocal no "almost always" as they state. However, they do "on occasion" offer trade in opportunities. Be sure and check their Current Promotions Page if you're feeling lucky.
