May 29, 2011 - Navigation map DVD disk read error - Suzuki 2007 XL-7 question. ... The only correction I've seen for this problem is to replace the radio itself. ... Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time ... Navigation system at Yukon xl 2008does not read the map DVD.

These links should help you out. 4,000 may be too specific, but I hope you get a good sense from the links.

Geography of United States Low Points

List of places on land with elevations below sea level

Also an FYI;

Badwater Basin is an endorheic basin in Death Valley National Park, Death Valley, Inyo County, California, noted as the lowest point in North America, with an elevation of 282 ft (86 m) below sea level. Mount Whitney, (with an elevation of 14,505 feet (4,421 m)) the highest point in the contiguous 48 United States, is only 84.6 miles (136 km) to the north west.

ill google for you.
read that, then ask what they mean.

107
MAP: 5 kPa, 37.5 mmHg or less (Low pressure-High vacuums-Low voltage)
the Map connect fell off , or was cut?
the reading 5KPa is insane low.

bad map or the vacuum port to it is blocked (gunk) or wires cut to it.

A barometric altimeter can be used with a topographic map to verify one's location and it is often more reliable than a GPS.
However, barometric pressure changes with weather, therefore hikers must recalibrate their altimeters every once in a while, when they reach a known altitude like a trail junction or a peak that is marked on the topographical map.

when was last time you had your system updated

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!

It could be the wires going to the map sensor are shorting out, you should check them. Hope this helps.

A theodolite is what is typically used in surveying to measure topographical angles.

You may be in an area where there is not enough topography for the topo lines to show up. Pan tothe Smokey Mountains and see if they show up.

tap on the wrench, tap on map, tap on about map, there you should see the base map checked, and the Europe map unchecked, uncheck the us map and check the europe map by tapping on the check box. leave the menu.
