I am currently refurbishing the front console /dashboard on the boat.
Is there any issue with the marine compass being immediately adjacent/ alongside the GPS unit? (combo GPS- depth sounder) ......Any chance of some errors creeping in to either device?
The GPS mounts are all aluminium and so metal shouldn't be an issue.......
Thanks

Calibration and adjustment can be tricky Bungarra.
Some thing that works is to stand behind the car away from metal at least a metre and note which way the needle is pointing - carry unit into car and move around to possible mounting
places and
check that needle still points to same direction.
In practise a small deviation is ok as most compasses and peoples use of them is only for general direction anyway.
Interesting to note is that often starting the car will cause a flick of the needle but it will probably settle in about same direction.
