I've ordered the eBay one from Germany, worked out I should only have to pay VAT, and a handling charge, so around £20, so still works out way cheaper than the Grom. Something to look forward to fitting. I was wondering if I could get to the connectors by pulling out the storage bin behind the seat that would house the speaker if I had the upgraded audio. Might be easier that pulling out the carpet in the boot, so worth a look.
