I use the TomTom One in the pocket method with headphones - although I can actually see the screen and operate it if I use it under the map cover on a scooter bag. The later thinner model of the Ones doesn’t have a headphone socket though.

www.pocketgpsworld.com is the website when it comes to satnav.
Ive got a Garmin i3, i think you can get them for £99 now. It is a ‘car only’ device but it so small its easily mounted on a bike, have a forum search on pocket gps and there are loads of mounts for it…
Or just stick it in a tank bag like me
