Why are the OS maps on a Garmin GPS unit not a higher resolution?

Why are the OS maps on a Garmin GPS unit not a higher resolution?
In this video I am going to address the questions - why are the OS maps on a Garmin GPS unit not higher resolution and what can you do to make them better?
Garmin GPS Units - gpstraining.co...
The x 5 questions I will answer -
00:00 - Introduction
01:07 - Why have OS maps on a Garmin GPS unit when you now get pre-loaded Topo Active maps?
01:55 - Why do the maps go pixelated if you zoom in to far?
Because they are Raster maps - scanned image of an OS map
Whereas the pre-loaded Topo Active maps are Vector maps
02:44 - What can I do to stop them pixelating?
Do not zoom in to far - 200 feet/ 60 metres
Shows you the scale of the map at top of screen or under the compass rose or other dashboard if you have set one up.
At that scale you are looking just under ¼ mile ahead, which is not very far at all, I tend to have the map page set at around 500 feet/ 120 metres, then I am looking ½ mile ahead of myself.
04:12 - How could Garmin stop this pixelating?
Stop people from Zooming in to much - as you can zoom in to 20 feet. 6 metres
05:30 - But is this relevant - should you be judging your GPS on the map quality?
No, as you have a navigational device not a moving map.
Don’t judge your GPS on map quality, judge it on the navigational experience it gives you.
This is one of the reasons I started doing the ‘walk and talk’ series - gpstraining.co...

thank you - very helpful

Garmin is based on the vector maps, though some units can raster maps too (not cycling Edge though). It'd be nice to compare TwoNav-raster orientated GPS units with Garmin.

The zoom is a problem with os maps.
when you have planned your route on basecamp and put it on your device the zooming in is still a problem because there might be 2 woodland paths close to each other so if you can't see the path you need clearly you will still be navigating your preloaded route until you see yourself drifting off the route line then you have to try and get back on the right path. That's why I use talkytoaster maps i can zoom right down and now they have updated them that well it's better than os maps in my opinion even show private land.

I disagree a little. I use my GPS as a map a lot of the time specifically in the lakes to see what other mountains are around, which villages are which etc
