Do you have to use it in hud mode? I had one a few years ago, you had to stick a gauze on the screen, which got in the way, or use it on the screen without, which caused a double image. I'd much rather have in on the dash as a simple visible gauge, like a pod.
My Tom Tom has been demoted to speedo, it's the only thing it's any good at
I use something similar on the car, unfortunately our 2001 ducato doesn't have an odb socket that i can find. The advantage is that they display the same as your speedo on the vehicle, so not affected by any gps signal issues.
I agree but you do have to be a bit careful because GPS can lose accuracy when it loses contact with some of the satellites. This is most likely to happen in narrow cuttings and sometimes with tree cover or tall buildings. The satellites are moving across the sky so loss of accuracy is not consistent and not confined to particular locations. I have noticed that the roadside speed displays agree with my GPS speed rather than my vehicle speedometer.
I suspect that this set up may be illegal in UK as your screen appears to impede your vision through the windscreen. certainly seen adverts for similar clamps on FB and many of the comments support my statement.
If his head whilst driving is at the same height as the phone you might be correct however I rather expect it's at least a couple of feet higher, I have a tablet holder with an 8" tablet in it on the dash above my steering wheel and can still see the bottom of my windscreen so no loss of forward vision, I also have a phone holder with the speed app displayed at just below eye level but it aligns with the windscreen pillar so again no loss of visibility.
Same here.
This one has to be used as a HUD as it has a reverse image. My projection screen is against the o/s windscreen pillar In my eyeline but not obstructing forward vision. Works a treat.
I have a 2021 Fiat, and plugging into the OBD port gives a variety of errors from the ECU. Generally the GPS speed is more accurate than the vehicle speedo, which always reads under the actual speed.

Yes it is the external brightness that is main problem. Checked this morning & when you are looking at the road ahead & transfer to the nextbase it is the same as walking from bright sun in to a dark room.you cannot see it .& it doesn't get any better as you are still looking towards the brightness all around the camera. & mine is same blue with 3" screen.
I sit well above the screen. Considering how many people you see with phones suckered to the windscreen at eye level it’s not an issue. And it’s not needed in the uk as I can read the MPH.
I went for the small size for an iPhone 11.
Pleased to hear that
Can any one tell me what app is best. I am currently in Austria heading to Slovenia in a Ducato and this would be great....
I use this one, give it a try and see what you think.
See my post #16, I have an iPhone.
Hi Diabalo.
. daughter got it from somewhere, i think she paid 11 Euros. It does what it says on the tin. Mounted/Stuck ( Sticker strip came with it 
) on a small piece of carpet square ,held down by a Self Tapper that is a tightish fit ( Not a mark to be seen) into the Air vent on top of the dashboard. So........ It would appear i am joining the " Tech " race at last. Works a treat. To be fair...... At that price i had my doubts,but, cross checking ( If and when ) i could see/read the Fiat speedo ,by taking my shoes and socks of,f an doing some counting/adding/subtracting counting my fingers and toes............. Its Spot on...... If using the Poles/Perches/Rods Display... JOKING !! 
We keep all of the windows in the back blacked out to stop reflections whilst driving
But you need a decent speedo at the warp speeds you cruise at.Hi Diabalo.
Ours is a HUD. but very similar to your unit,but not as Posh..
Tea Bag.
PS. " An old Blaster Bates " Tale..... The police were following him and pulled him over,he said.." I KNEW i was only doing 30mph cos' the ammeter was charging at 15 Amps... "
I have no real windows in the back & black out curtains behind cab seats. It is the sheer brilliance of the sun coming through the windscreen. I had to fit an external sun visor to reduce the amount at the highest point.It ,hopefully,will be far better when I fit a 'slide out' to my sun visor to fill the gap between the two visors.

I use the Speedometer 55 app and upgraded to the Pro version. It’s so much easier to read than the van speedometer. You can customise the display to show various other information too (heading, altitude, date, time etc). Kph or mph. Optional speed alerts. I use it every time I drive.
