The GPS reception is actually quite similar between the vehicles.
If you look you see that the signal for satellite 18 is virtually identical on both vehicles. And satellite 26 is nearly the same as well. So that means antenna performance is similar. As the photos were taken 7 minutes apart from each other, signals can vary.
Base on the S/N data, I would state that your antenna is OK.
But maybe it is intermittently failing.
You best way forward is, in order of cost and likelihood:
1. Check GPS antenna connector is properly plugged in at antenna and at nav
2. Replace GPS antenna with a new one (cheapest option)
3. Replace GPS receiver with a new one (costs more than antenna)
4. Replace entire nav - if you want to.
