SOURCE: gpsmap 182c

My 182C developed the same problem. It appears to be a problem with reading data from the card. When I power up the unit, sometimes it will display "Reading Card" for a long time and no data will be read. I've found that if I open the latch and push in on the card as I press the power button, it will only then display the number of maps loaded. Sometimes less than other times. Most times a lot of data is not loaded from the card causing the problem frankcps describes and other problems, such as no data for tide stations, anchorage, etc. I tried cleaning the contacts on the data card & where it plugs in, but still continue to have the problem.

SOURCE: 1300 nuvi screen comes up loading maps and stops...

A Garmin Nuvi 1300 that freezes on 'loading maps,' or is acting erratically is symptomatic of having corrupt firmware.

To correct this, I recommend backing up your favorites, clearing all user data, and if it still is stuck, then updating your Nuvi firmware.

Follow these three steps to take to get your Garmin Nuvi 1300 running like new:

  1. Back up your Favorites.
  2. Perform a Hard Reset.
  3. Download and then run Garmin WebUpdater to replace its firmware / system software.

I hope that helps.

Where do i go to down load update for my gps 295. garmin said thay dont support this unit. thanks joe


Joe,

The Garmin "GPSMap 295" is at, as far as Garmin is concerned anyway, "end of life". This means Garmin will no longer support, repair, etc. this product. C'est la vie.

Garmin's older product lines lack the hardware to decompress the new "NT" (New Technology) maps that Navtek (the map company) is producing now. The NT maps are compressed so that they would fit on smaller capacity memory cards. By doing this, the maps required Garmin to include hardware (special designed circuitry) that could quickly decompress these maps "on the fly" for display. The much of Garmin's older GPSMap & StreetPilot lines predate this hardware requirement.

Our "still-functioning" GPSMap & StreetPilot GPSr will still pinpoint our location on the Earth as always - but lack the latest & greatest maps. You should review the maps that your GPSr can use and choose the one you prefer. I switched mine to display topographical maps. These show many of the road names like the City Navigator maps do, but lack important things like the POIs and routing. If you can do without them, this could be good enough. If you can't, you'll need to decide on whether the last non-NT map version is sufficient or purchase a new GPS that can accept the maps you want to put into it.

I hope this helps and good luck!

Chat session ended by mistake. I need help with getting my Garmin GPSMAP 60 CX up and running. 1. I have successfully loaded Trip and Waypoint Manager on the computer 2. I have the unit hooked up to the...


You cannot load maps to the unit using the Trip and Waypoint Manager software. That software only does what it's called - it transfers routes and waypoints. To install maps onto your GPS, you will need Mapsource, which normally comes with the maps. Once it's installed on your PC, you hook up your GPS with a mini-USB cable, choose which maps you want transferred to the unit, and then the Mapsource software will knit the map segments together and transfer them over to the unit. Hope this helps.

Using dnr garmin or map source how do I transfer from excel


I've just had to do this. Somewhat annoying and I'm sure there must be a quicker way. Let me know if you find one. <br /><br />Firstly you need ArcGIS or something that can create .shp files. Load the Excel file into this. In Arc you need to right click the table and display the x y data (just to make sure it's all okay). Then save as a layer. Then export as an .shp file. <br /><br />You can the open the.shp in DNRGarmin and upload to your GPS..,<br /> <!-- from fixya rte -->

GARMIN 60CX Contour Map display: Sent maps to unit OK. Then was able to display a WayPoint with its contours. However... later, now able to display WayPoint but NOT surrounding contours. The Map IS...


The topo maps are low in the map hierarchy. If another mapset is loaded at the same time and is also checked it will likely "cover" topo. I think the Recreation maps are the only one's lower in the hierarchy.

You can't turn the navigation back on with this method. You must once again highlight the waypoint you want to navigate to in your Fine>Waypoints screen and then press the "Go to" highlighted button on the screen.

Have problems with the loading of the map XPC415S. Australia East coast. Will this map work with this unit?


Any bluechart that has been preloaded on an SD card should work.  Did you purchase your chip with the data preloaded or did you download it yourself?  If you downloaded it yourself, try erasing the sd card, format it, then insert the blank card in the 420 and power it up. This somehow preps the chip for the data download.  Then download the bluechart onto the chip and try again.  There is some ambiguous wording in the download screen that makes it look like some kind of error, try the download anyway and most of the time it will work. After the download is complete it should list the bluechart software version on the screen along with some other software info.  If the operating system software is not v2.5 or higher, you may need to download a software update first.
