I went looking an e-bay for a 256 Mb data card for my SP3 earlier, but there were none advertised in the UK. However there was a link to at least 7 cards advertised on the German e-bay site - perhaps not surprisingly, these were cheaper than the ones I've seen advertised on the UK site. These are produced by Garmin, so I'm assuming they will be compatible with my SP3 - unless anyone from here knows better. My German is non existant, so I can't tell from the descriptions whether they would work or not. Any comments etc would be welcome, before I bid on anything and possibly make a tit of myself.
