Thread: About 37xx converted to 34xx satellites reception accuracy

I convert 34xx to 37xx and then back

I try all that i think of but i have accuracy 7-15m ( before 3-5), then i see this settings for Predicted EPH and cold start.
I set this settings but no difference when i have satellite lock.
Then i turn off and back on nuvi and go to satellite page and whait for satellite lock.
First was 133m accuracy then go down to 3-5m.
I again turn off and back on nuvi and go to satellite page and after 10 sec i have 3-5m accuracy
Every time when i start nuvi i have now 3-5m like before flashing.

So this is procedure:
Go to height page and set Predicted EPH and cold start (you set this only one time)
Go to satellite page and whait for satellite lock
Turn off and then again on your nuvi.
Go to satellite page and whait for satellite lock (after 1-2 min you will have 3-5m accuracy)
Turn off and then again on nuvi and you will have satellite lock in about 10sec with 3-5m accuracy

When you again convert nuvi to 37xx or to 34xx, then you must use again above procedure, but if you flash 37xx to 34xx and you stay on 34xx then you do this only one time.

p.s.
I have Pc beside window and have 3-5m accuracy in my room
I don't know if i have only luck, but this procedure work for me, i hope that will work also for other people.
