After the most recent update I have encountered two major problems:

1. The device keeps switching itself off and then on again. Sometimes
it remembers the route it was following, other times not.

2. The speed limit of the road I'm travelling on shows as 59 instead of
60 or 71 instead of 70 !

Anyone else had this/these problems ?

I will, of course, get on to TomTom but there seems to be some very
knowledgeable people in this group who will probably reply a lot faster.

Hi Walt

I have same with my 930T, following are instructions I received from TomTom
to cure the problem. However when I tried it there were problems with the
web pages last weekend and I had to guess some of the steps (reset and
back-up instructions) and have noticed that the unit is still rebooting
occasionally. I also tried it on my old 500 but ended up without any maps
so I just copied all the files from the back up onto the 500. I am going to
try it again this weekend but if you get it to work please post here.

Here is the text from the email from TomTom support.
It could sometimes happen that a minor file on your TomTom becomes corrupt
and this could lead your TomTom to function incorrectly.

navigating with your TomTom. These steps might look a little complicated so
