Is there a Navcore available to run on a Microsoft Nokia Windows 8.1 phone with a display resolution of 800 x 480?
Thanks in anticipation.

Not sure if you noticed but a Navcore works under Linux and the TT app under Android.
Get a proper phone with a proper OS and try again

Please answer the question rather than air your prejudices;-)

There is an old saying: Ask a stupid question and you will get a stupid answer.
The phone runs on Windows, a Navcore on Linux, therefor the question is of no relevance.
I guess when you look for software for your phone you don't search for Linux programs, do you?

The my OP may or may not be stupid. I've certainly received two stupid answers.

Sorry if you feel that way but a simple Google search would have shown there is no TT for Windows phones / tablets.
Also that there is no normal Windows version for TT.
A Navcore is a dedicated piece of software for PNA's.
The display resolution or type of phone are not relevant.
You could have avoided the question and answers with a very simple Google search or by checking the TT homepage for Windows support

pace your statement "there is no normal Windows version for TT"...............
I am currently running Navcore 7.9xx on a Windows 6.5 phone which has a smaller screen than that described in the OP. The essence of the query is whether there is a version compatible with Windows 8.1 and suitable for a higher resolution screen.

TomTom has not developed an app for Windows Phone 7 or above:

If you have a Nokia Lumia, you could use the Nokia HERE Maps app which is not too bad actually...and you get free maps

Windows mobile 6.5 is wince 5 based, windows phone 8 and above isn't.

I guess what people throws off here is Microsoft.
If you say Windows it does not always mean what the other person thinks.
Also when people see that a device runs on Windows they simply assume it must be the same Windows on everything.
Just a few "Windows": CE, WM, XP, Vista, 3.XX, 95....
The only thing they have in common is a screen that has the look of a window
But this neither means they work the same way, not that a program for one version has to work on other versions too.
If a user on top of that has no clue for what type of OS a program is available the chaos is perfect
