St220 Denso Sat Nav Unit A204 Error

[mrrossdude]

Hi there,

Just got a 53 plate Mondeo ST220 with the Denso touchscreen sat nav/radio/cd unit.

The sat nav is showing a symbol with a globe with a cross through it, displaying apparently that it cannot get GPS signal.

I have also entered the error screen and noticed it has an $A204 error, which I believe is an error with the aerial/gps mast.

Looking further into the diagnostic screen though, it seems to show that I can actually "see" quite a few satellites.

I'm confused as to why it would be the aerial aswell, given the fact that the radio works perfectly.

Anybody got any idea? Was going to buy a new mast and antenna off of eBay, but the ones that actually support GPS are expensive by my standards.

Cheers.

That code is for an antenna fault, sometimes a very small amount of corrosion can cause a confused signal or even no signal at all.

I reckon you need to replace your antenna mount.
