Use magnets to nullify magnetic field ?
(OP)
This is not a professional question:
I used 3 rare earth magnets to install a steel bracket in my track vehicle to support a GPS track timing system. the 3 magnets are fastened to a horizontal plastic surface with Gorilla brand double sided mounting tape. The wide steel bracket is L shaped providing a vertical surface to mount the timing device. The timing device itself has 2 rare earth magnets imbedded in the back for fastening to a steel vertical surface.
Question: The steel bracket is mildly magnetized from the 3 magnets that hold it in the vehicle. Would adding magnets to the steel bracket in the correct location and polarity, partially nullify the magnetic field around the steel bracket that may affect the timing system ?

It is receiving radio timing transmissions to do its job.
For maximum holding though there are two things to address.
1. large contact area so that it can't tip
2. the mounted magnets should align, and be in opposite polarity to the ones on the bracket
It would even be better if you had mounted the magnets to a piece of steel. You only have holding force when the magnetic circuit is closed.

Thank You again

Even with a magnetic filed pass through your GPS, you are probably still fine because GPS receives satellite signals.
Strictly speaking, however, a magnet could affect a GPS if it has a built-in hard diver and memory card. Also, a very strong magnetic field could disturb electrons to affect a GPS.

Most electronic circuits can withstand magnetic fields that are essentially impossible for ordinary people to generate; i.e., they require either a nuclear explosion or an EMP generator to cause disruption or damage.
