Some versions of the TomTom ONE 3rd Edition have limited internal memory(no memory card slot).

connect your device to TomTom Home to check how much memory you have available and check the map is not too big for the internal memory

I was having a similar problem where i would go through the setup screens until I was selecting the map and then it would restart.  What worked for me was to connect it to my computer and choose Operate My Device from the third page of options in TomTom Home.  This let me progress through the remaining set up screens and get to the point where I could enter an addres again.
Don't know if this will work for everyone, but it seems to have done the trick for me.

I take no responsibility if you damage your tt in this procedure.
To open the tt one third edition and change the battery you will need a # 8 and a # 6 torx bit. Remove the 4 # 8 torx screws on the back of your tt. After removing the screws carefully insert a guitar pic between the two halves starting at the top and continue around to the sides. Be careful so you don't damage the case. After you have gotten the three sides loose (top, right side, and left side gently pull the two halves apart from the top (be very careful at this point so you don't dislodge the USB port). Do NOT take it completely apart at this point because you have to remove the battery and speaker connections (they just pull out with a little wiggling motion). After you have taken the case apart and disconnected the battery and speaker cables you will need a # 6 torx to remove the board (don't skip this step because the battery is held in with two sided tape and you have to pry the battery out). Now that the board has been removed take a small screwdriver and pry up on the battery. Now all you have to do is reassemble your tt in the reverse order. Just remember the smaller screws are for the board
