had the same problem, i updated my map of western europe. When i turned my tom tom 730 on, it would not see the map.
my solution: I took the SD card out and put it directin in my coputer. that promts tom tom home to open.
I updated my divice (the SD card ) via tom tom home. that way i think it copies the program itself on the SD card
remove SD card from computer, back in tomtom device, start up. still no map of western europe
repeat: revome SD card from tomtom, back in cokmputer: update again ( i guess it updates something different now)
SD card back in tomtom: IT WORKS !!
hope that helps

I have the same problem,
No maps found after update, downloading the maps again doesn' help. I don't have another memory card reader so I cannot try connecting the SD card to the computer without the TomTom navigator.
It is very frustrating that the TomTom user guide doesn't even have any kind of troubleshooting section, so answers to any problems must be searched from this forum.

I have tried everything on previous pages. i think that there is a file missing because i have had a look at the files and also the file currentmap.dat is still showing as my old map of gb & ireland so i think that the issue is with the install. Bit of a pain as i am leaving for Europe today and now have no map

I've had the same problem - "no maps found" message after updating the maps.
The solution in my case was to remove the navigator software from the device and from the backup on the computer. Then the software is listed in the list of available updates. Download and install it (this took two rounds of downloading and restarting the device) - and make sure it installs on the hard disk, not the memory card (it should do that automatically). After that I could use the maps again.
This was because the old software could not read the updated maps, and TomTom Home did not understand that the software should be updated.

I'm very much a newbie to TomTom Forums and the GPS itself. In fact, this is my first ever car and GPS.
This is kind of relevant to this question.
I have a TomTom ViA 1605TM. I updated the current US/ Canada map on the internal storage.
Bought a new 16GB Micro SDHC card. Inserted it into my phone (don't have any other adapter to use to put it into the computer), and then formatted it from there. There is no data on the SD Card.
Then I inserted it into the TomTom. I see the message "Checking the SD Card" on the TomTom, but NOTHING on the computer.
I did the following:
- removed the SD Card, turned off the laptop
- turned on the laptop
- started MyTom Tom.
- inserted the SD card and connected the Tom Tom to the laptop
Put the SD card in my mobile to test if it works there - a second time. Yes, I am able to see the card, and 14.9 GB of usable storage.
What am I doing wrong and what needs to be done for me to see the SD card that I insert into the GPS, in my laptop as a removable device?
Once the above could be resolved, I have additional questions:'
1. How to move maps from internal storage to the SD card? I see that MyTomTom stores the data under C:\Users\<<username>\AppData\Local\TomTom\HO
2. Can I play music from the GPS? If so, what is the process?
Thank you to all who read and respond to this query.

Welcome to the forum kach1947
To format your SDHC card your need to insert it into the slot and perform a Soft-reset
Your device will recognize the new card and ask to format it to which you answer "Yes"
Once formatted in TomTom proprietary format, you will not to be able to read the card on any computer.
To Answer your additional questions
A1) MyTomTom decides where to place maps, not the user, as it only uses the card if the internal drive has insufficient space to place a downloaded new map.
A2) Unfortunately none of the new NAV3/NAV4 device are able to play media files
