Reframing my Question for RESTful 3rd Party WebService

Question

My last posted question did not produce any feedback for what I was looking for, so I'm trying this again.
I have a Driver entity, and an gpsVehicleData entity. Drivers can have one gpsVehicleData (relationship)
In a grid screen I use; for THE most basic understanding I can get, I have one field I need updated from my 3rd party webservice. We'll call it gpsVehicleData.MotionStatus, and I need to use Driver.DriverID in the service to find his MotionStatus.
This is the example connection snippet I was given by the vendor.
Dim responseData As String = ""
Dim uri As String = "http://ws.samplegps.com/DriverWebService.svc/drivers/"
Dim request As System.Net.HttpWebRequest = Net.HttpWebRequest.Create(uri)
request.Method = "GET"
Dim companyLoginId As String = "12345"
Dim username As String = "John"
Dim password As String = "Doe4321"
Dim auth As String = companyLoginId + "|" + username + ":" + password
Dim authHeader As String = Convert.ToBase64String(System.Text.Encoding.UTF8.GetBytes(auth))
request.Headers("Authorization") = authHeader
Try
Dim httpWebResponse As System.Net.HttpWebResponse = request.GetResponse()
If httpWebResponse.StatusCode = Net.HttpStatusCode.OK Then
Dim responseStream As IO.StreamReader = New IO.StreamReader(httpWebResponse.GetResponseStream())
responseData = responseStream.ReadToEnd()
Console.WriteLine(responseData)
Console.ReadKey()
End If
Catch ex As Exception
responseData = "An error occured: " & ex.Message
Console.WriteLine(responseData)
Console.ReadKey()
Great. So this works when I run in it's own solution, and it pops up a console window and shows all data for each of my drivers. My problem is, I cannot find an example I can follow to update the Motion property in EACH ROW (each driver of my Screen with
this snippet.
(A button function seems appropriate instead of Validate method, but honestly as long as it works I don't care.
This is the closest I have found but I'm not using Soap.

This is too, but much different than the first example!
Calling Web Services to Validate Data in Visual Studio LightSwitch
One example has something and not the other, and the other example has this but not that. Very frustrating for a new person!
I do not need to dive into RIA right now which has been suggested before.
I know I am not very knowledgeable in VB, but I need to use something applicable to my environment I can make more sense of. Thanks in advance

From your description, you can consider using method above, as I know, this way is available/convenient for your situation.
