Only Magellan Triton 400, Triton 500, Triton 15 have SD support an can handle large raster maps (20MB) Please take notice: The Explorist GC requires the current firmware (Version 2.13) to display detail and basemaps.The underlying data has its origin only in license cost free sources as e.g.Fixed an issue with missing contour lines on some maps.
Nowhere in the loading directions does it tell you that you have to leave the SD card in the unit.
We only found this out by my husband writing to Magellan.
Buy Magellan only if you want useless junk equipped with frustration and headaches. Recently, the company has discontinued support of 'Content Manager' that allowed the user to easily and quickly update the content of the GPS.
They have replaced it with a web product that is slow and cumbersome to use. Their new solution is far too difficult and time consuming to use.
Maps4me is the worldwide largest repository for license cost free maps for Magellan GPS units.
These for download available maps for the Triton and Explorist are license cost free.Magellan GPS 5230T-LM effectively killed my unit --- support is a bad joke --- told me they don't support Win10 & said only solution was for me to buy and install win7. Their new web based Content Manager did only to update maps - was useless since the update was so old.I was told that the only feature that worked on new CM was map updates. I used the Magellan Road Master 6265T-LMB for a long time.We are finding the upgrade is not very user-friendly, full of erratic directions and has to be reset from the beginning if we stop at a rest area on the interstate, rather than being able to 'resume'.There are newly expanded POI's and POI categories, but directions on getting to them often requires 'making a legal u-turn'...which isn't necessary. I purchased this because my unit, although only one year old, came with a 2007 map which did not recognize some major construction projects in the area in which I live. The map has provided incorrect and "odd" routes on several occasions since installed.All maps loaded by the user can be deleted from the device or Vantage Point.
