OK – positive update time…
I was getting nowhere with Garmin email or phone support. They even sent me conflicting emails within 30 mins of each other – one saying send it back and we’ll look in to is, the other stating they still want £74 for a replacement. To cut a long story short, I sent it back to them with a bit of a stroppy letter, and hey-presto, they just sent me a refurb unit, not cost! So, after a bit of effort it all worked out fine.
However, in parallel, I tried johnneyboys advice and also contacted Amazon. They were amazing – no questions whatsoever and sent me out a brand new full replacement (full Performance and Nav bundle), so now I have 2!
Anyone want a brand new one of these?

Garmin 800, inc Cadence sensor, Heart Rate monitor, brackets etc, all brand new, boxed?
Happy days,
