I'll try entering the names of the intersections and see what happens. it does the same as Google. once you start typing a letter, it tries to link up to what it thinks you want. I had airports on my mind and didn't think to do that.....

Ok, that seems to work. took a while, I forgot Maylay is now Mayfield. it couldn't find Maylay.

Now, this is a little different than the Garmin 500. I think this one is the 530. I can't activate the path, but I'm half way there though 

Another learning curve to get around...

Funny! Would this help?

That would do it......I found both intersections. I'm going to watch a You Tube tutorial on the 530...

Ok, I was able to some what set the GPS. I flew from Malay to Canby. it gave a "Desired Track" of 161 degrees......I ran right into the intersection.

I was in a King90 twin engine, so speed, and time was not the issue.

Presumably, you were not plugging any winds aloft information into the system.  So here is where that 161 degrees came from.  As we have discussed previously, the Canby Intersection is a few hundred feet WEST of the Malay Intersection so the True Course between them would be 180 degrees or straight SOUTH for all practical purposes.

I have a several year old FAA Sectional Map of the Portland area and it gives the Magnetic Variation as 17:00 to 17:30 degrees EAST for that time.  Today, that Magnetic Variation is probably up to around 19 degrees EAST.

So to determine the Magnetic Course (which is what you will see on your Heading Indicator on the GPS with no wind), the EAST Magnetic Variation of about 19 degrees must be subtracted from the 180 degrees True Course.  The end result is your Heading Indicator will show 161 degrees Magnetic Course.

If the Magnetic Variation was WEST, then its value would have been added to the True Course value.  It should also be noted that VORTACS "NORTH" is actually Magnetic North which is a wandering point somewhere North of Greenland.  This all means that maps have to be updated regularly and that the radials from VORTACS change when the updates to Magnetic North are made.

 

The C90 always wants to roll to the left?

You might want to enlarge the screen to see the Garmin a little better...

The Garmin GPS is an amazing tool. I just wish it was on the 727 for testing purposes. I can program the Garmin in the C90, or Baron 58, and take off with my tablet on, and the plane will fly the course given. I set it for Seattle to Malay, and then to PDX. I just put the tablet in front of me by my computer, and continue to surf the net while watching the plane 5 feet away of the cockpit on my Samsung tablet. 

Once you set the Garmin, I just takeoff and reach the desired altitude, and pop on the auto pilot, and the altitude hold, and the plane flies all by itself.... the video above didn't have the auto pilot engaged. I just followed it's course telling me when I drifted off of the given course. you have to engage the auto pilot, and the "Nav" button for it to link to the Garmin, then push the "Alt" button to hold the altitude.,

The auto pilot works good in the 727, but wind will still cause it to drift off course....

Can't the auto pilot be set to track direct to a VORTAC or a Waypoint (such as an Intersection)?

I have a PDF I downloaded a while back. here is what they say about the auto pilot....

The Autopilot (A/P) can control the aircraft in a climb, cruise decent and
approach phases of flight or as directed manually by the pilot via the control
knob. It may also be directed by signals from the VHF, GPS, and INS
navigation systems. It can also find and maintain a pre selected heading,
altitude, pitch attitude or operate in a split axis configuration.
It requires 115V AC for operation from the aircraft generators or an external
source. If using the latter you need to operate the ground test switch.
Electrical interlocks prevent selection or operation unless all the proper
conditions for correct functioning are satisfied.

I have been using it for a while, but I only engage it for a straight course. I use the control knob to turn with, which doesn't occur a lot till I pass Merwin lake.

Here is an interesting article.....

Due to poor visibility, his descent went unnoticed by the United States Air Force F-106 jet fighters tracking the airliner. He was initally believed to have landed southeast of the town of Ariel by the edge of Lake Merwin, 30 miles north of Portland, Oregon. Later pilot information puts the jump location about 20 miles further west. This marker is at approximately that point.
