Hi sidtmedid, I’ve cut up a piece of aluminium to fit behind the satnav, which mad little difference until I connected it using a wire to the bikes frame, that improved the signal but not as much as covering the dash with aluminium foil. I need to find a permanent earth point (handlebars aren’t earthed, there must be some grease in the steering head bearings ! ) then I will test it on the road. It’s odd, every part of the bike has a label on with noise and interference specs except the dashboard.
My XT is mounted high using the Givi phone bracket FB8203. It’s on the Garmin mount (which is garbage btw, the pins are far too fragile) and powered from a tail taken off the USB power line behind the headlight. I don’t get any interference with this - but then, I’ve not got MIA.
Thank MrB1967, looks like you have the earlier dashboard if you are using the Givi FB8203, mine is the later (2024/2025) model with the same dashboard as the V100 Mandello. I tried holding my XT above my dashboard and the signal strength is still greatly reduced. I have yet to disconnect the MIA which is mounted under the passenger seat but may be causing the issue.
If the MIA is interfering the direction of the problem will be towards the seat rather than the dash i would expect.
That would be the logical thing, but it may well be that the MIA unit activates a bluetooth module or similar within the dashboard. I will update once I have tested disconnecting it.
