Hi, just bought a TT One (z1230) I've installed TT Home on a PC I have full admin rights but the PC does not detect the Tom Tom at all. Once it showed on the TT screen that to 'connect to a computer I needed to go to Tom Tom website / get started' but otherwise nothing on PC or TT.

I've been into device manager and its not seeing the TT as a disk drive (have done a scan, nothing)
Also been into Computer Mgmt and Disk Drives and nothing showing. There are two unnamed volumes :
300mb Healthy status (Recovery Partition)
512MB Healthy (EFI System Partition)

But both are present if I remove the TT and I think they are system areas.

Devices maps are from 2012 and I want to update the device - any help gratefully received.


Connecting an old TT ONE to the PC with a functional data cable should always cause it to show up as an external drive, much like a thumb drive.
Apart from a cable issue, it gets difficult to resolve.
Obviously, try a full reset of the device while it's connected to the PC.
Would help to know which of the many ONE models you have. Could you please provide the first two characters of the device's serial number? Your 512MB partition may be your device. Some 'regional' models sold in the UK only had 512MB of memory (just enough to handle the UK maps) back in the day.

And a word - which may make all of this moot - TT has stopped supporting the devices with really small memory for new maps. They've added so much new geometry that it's beyond their ability to fit it all onto the little devices now. That said, they may still supply the last map from earlier this year.
While TT will be producing no NEW maps for these devices, isn't it still possible to update to the last production map for them? The OP talks about being back in 2012 with his device, so even picking up the last production map from late 2016 or early 2017 would be helpful.
Don't think that is going to be possible either. In fact, a second wave of older devices is to be included (including some Nav 3 devices) in early January. No more maps or other services. See this list:

I was just wondering if they were still making available the last available production map that they had from about a year ago. Would have been nice to continue that for a little while longer. Certainly doesn't occupy much server space!
