Hello & Welcome,
Sorry I didn't see your question earlier and to hear of any issue you are having with your device.
To help you with this issue, may I ask:
1) The FULL Make & Model Number of the device you are working with?
2) The AGE of the device?
3) WHEN this issue first began?
Hi again and thanks for that information.
Dezl 560 is a valid model number, so I will go with that.
OK - in the time you have owned and used the device, have you EVER updated the device software OR installed a memory card in the device (microSD card)?
I see your request for a Premium Service (phone call), but I'm not near a phone at this moment to be able to do that. But another expert may take accept your request at any time.
If you would like to continue here in this "chat" format, please let me know if the device software has ever been updated or if a memory card has ever been installed in the device.
OK - according to my notes, this device has a "slit" on the left side of the unit that will allow you to add more memory capacity to the device.
I mention this because the symptoms you mentioned (trip planning issues) often occur when the internal memory starts to get full. Here is a link to where you can get these cards at a reasonable cost.

Now since I believe this is really a memory issue, you can also try doing a "master reset" of the device, which will clear all the user data (including trip memory), and should allow the trip planning to function normally again.
NOTE: You may want to BACK UP and favorites you have stored in the device BEFORE doing the Master reset, so those favorites can be restored afterward.
Here is a link to a video that shows how to do the master reset.
NOTE: This should be done when the device is fully charged but NOT connected to power.

Please give these steps a try and then TEST to see if you can plan a short trip, then a medium length trip, etc.
Please let me know what happens when you try these things or if you have any more questions.
Thanks, ***** *****
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved?
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
