Updating maps on nuvi
When you do, instruct the nuvi to stop routing, power it off, unplug it, plug back in, power back on and reroute.
Garmin offer free map updates as part of their nu Maps Guarantee.
The nu Maps Guarantee lets customers get a Nuvi map update for free and state that: “Simply connect your new Garmin Nuvi or Zumo to your computer and visit within 90 days of first acquiring satellites while driving with your device and you’ll be able to see if a free map update is available.” What this essentially means is Garmin will offer the customer a one-off map update for free within the first three months of them owning and using their Nuvi GPS.
That was a bummer, so I needed an alternative backup unit that could support more map data. The going price is between $25 to $30 to get one with mount and bracket, so what I paid was fair. It just so happened that a 200 model is what was available, so that's what I bought. That means solid, fast GPS signal acquisition, and that works just as good today as it did back in 2007. The maximum memory card storage the nuvi 2x0 series can support is 8GB, so the 8GB micro SD card w/SD adapter is what's needed. Additional note: All the older Street Pilot models, meaning the i2, i3, i5, c310, c330, c340, c550 and c580 have a 2GB cap on the SD storage it will support. In other words, for full use of the OSM maps, a nuvi is required since it can support 8GB. Bing Maps is without question the easiest when it comes to getting coordinates.
After that, all it takes is stuffing the memory card full of free OSM map data. First, I didn't feel like spending the money on a new one. Garmin will attend to the bugs and release patches as they always do, but new-model bugs are not something I want to deal with. Find a spot on the map, right-click and ta-da, instant coordinate info: For any instance where a street address can't be mapped, the coordinates can be mapped. Use a 2D "Track Up" or "North Up" map view Using 2D gets more usable (keyword there) map info on the screen and in many instances is easier to read on a 3.5-inch screen. Update the firmware (only if the battery still holds a charge) Do a Google search for "Garmin Web Updater," download that, install it and use to update your old nuvi to the last-released firmware for it. Do so on yours, as it will apply necessary patches.
Currently, I have a nuvi 40LM and a decidedly old Street Pilot i5, which I'll talk about more in a moment.
