Hi, I purchased a used RNS-e on eBay and typically the unit that was described as in mint condition and fully functional has a broken dvd drive. Strangely enough, the seller also forgot to send me the navigation disc. hmmmm Anyway, I have taken the top off and found a little piece of plastic sitting on top of the broken drive. My guess is that the mechanics of the drive have broken and if I can find the home for this little piece of plastic I might get it to work again. My problem is that I dont have a reference to compare the drive to. If anybody could post some very close up shots of the rns-e internals, that would be great.
