I had ordered everything by then, and received everything apart from the GPS dongle.
If any dongle chipset is wrong I can always send it back for a refund and get it from elsewhere. Although I didnt do it for cost reasons, sourcing the various bits separately was about £10 cheaper in the end I think, but yeah, buying from ebay is always a bit of a gamble for these things, not being sure if the 'UK versions' are the same but marked up in price, or there are counterfeit items from China. I buy all memory cards etc from amazon now as that is definitely one area where there are too many fakes on ebay!
