There's no reason why you can't do that (Plug into din), but remember to unplug it every time.
The tomtom mounts have a bit of a habit of tricking the can bus system into thinking there's a charger plugged in and the socket stays live rather than switching off after a few seconds.
The outcome is that the 12v to 5v transformer built into the mount stays live and slowly but very surely drains your battery.
Very much neater to set up a fuse panel to drive al accessories and use a relay to switch it on with the ignition. Positive ignition feeds can be taken from the sidelight, tail light, or my preferred green wire on the diagnostic socket.

Thanks for that. Only thing i would be worried about is water getting in tom tom from were the wire comes out on the back. No hassle to unplug it.
Are you referring to the mini usb connection, not the DIN plug referred to in your OP?

I’m no expert on TomTom devices but I’d be mildly surprised if someone doesn’t make a waterproof case for one.
As you have a 1600B, wouldn’t it be easier to use the cradle BMW built into the bike’s dashboard? OK that would require using a Garmin but you can pick up Garmin devices secondhand pretty cheaply.
Yes,mini usb connection on back of tom tom.
I think the responses thus far are based on your reference to the DIN plug and not the mini-USB that you intended to state.
The mini-USB socket is covered, when not in use, by a rubber sealing plug. A key purpose of that plug, I would suggest, is to prevent water entering the device.
Better to mount it properly and power it as it was intended to be used. However if you only ride in the dry, you should be ok.
Assuming the DiN plug socket kicks out the correct voltage and amperage and is somehow suitably fused, it will be fine.
