From a friend - All bullet drop depends on the bullet weight, load and barrel. So, a 450 bushmaster with 20" barrel on it and done some work with it the past few days. After some trouble dialing in the scope multiple times I finally got it on at 100 yards. With a 100 yard zero (around 1.5" groups which isn't too good but I believe it is due to my scope which is going to get replaced shortly) we shot it out at 300 yards to see what it would do. We calculated the drop to be approximately 30" with the 100 yard zero. First few shots we were not on paper so we raised hold point up a few inches and we had our first mark. After 2 more shots we had a group to measure from. Back at the house we measured the 3 shot group at 300 yards to be 7.5 inches. (again I am confident this can perform better with a better optic) and 37.5" low. With a 2000 fps velocity and 250 gr bullet from Hornady, it puts the ballistics at
100 yrds- 0" drop, 2030 ft lbs energy, 1912 fps
200 yrds- 9.5" drop, 1067 ft lbs energy, 1386 fps
300 yrds- 37.5" drop, 760 ft obs energy, 1170 fps
Most air conditioners now are reverse cycle, which means that they can heat as well as cool. Cooling only units were popular many years ago due to the price difference for a reverse cycle. Today, the cost of manufacturing has dropped and it has resulted in cooling only units being virtually finished. I would suggest you get a local air con sales company to come to your house to measure up properly and determine what would be best. There are a lot of factors in installing air conditioning. IE/ The size of the house, the area it will be required to heat / cool, the amount of windows, types of walls, roof etc (Heat loading on the house) Roof and wall insulation etc etc.
to create a proximity alarm for one of your waypoints is a very simple process. First you will want to create a waypoint for you destination. Be sure to name the waypoint something that will remind you of the destination. After this is done go to your main menu by pressing the "menu" button 2 times. Navigate to the "proximity" icon select it by pressing "enter" it will now allow you to create a proximity alarm select the open space and press "enter" it will now give you a list of items you can use select "waypoint" using "enter" and pick the waypoint you created earlier. now all you will have do is select a radius for thee alarm. You can also use the other items to create your proximity alarm such as cites addresses and any other navigation category.

OR
From the Home screen, select Information > User Data > Waypoints.
2. Select the waypoint or the MOB you want to delete.
3. Select Review > Delete (The Review button is only shown when more than one waypoint
is in the vicinity.)
You may need to update your maps. If they are up to date (2010) then its just bad data from Navteq. You can add the waypoint in your nuvi and custom name it which would provide better results.
Sorry for late reply. You need to select an area on your topo map prior to downloading it. For example, if you plan to go to Algonquin Bice Lake (access point 4), then you need to select the map around the area (starting from) Kearney upto the Magnetawan Lake and beyond. Mark waypoints from the put-in to the campsite on Bice Lake (best to compare of the topo and Algonquin canoeing map). Then you can click Transfer, click Send to Device (GPS 76cs should appear) to download it. On the GPS, enter the Find Waypoint button and you should be able to see those waypoints. Good luck for your next trip.
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.
