You will find for around £200 that you should be able to source an end of line Garmin Nuvi 300, which will do all of the above, with free for life updates.....
ETA - the unit is really slim and fits easily into your pocket, plus you can look a complete IT Geek and continue your journey on foot to get right to the door of your target destination ( even changing to pedestrian setting so it will adjust the eta..)
I find that the best place is the lower offside of the screen.
The unit ships with what at first glance looks a somewhat flimsy mount, but I assure you it's gives a better suck than a Dyson, and will hold the unit in place no matter what.
Also provided is a charge cable long enough to keep managed and out of the way.
ThIs arrangement maintains an ease of use in situ, which is another bonus.
