I recently inherited a GO520 which was in a bad way - wouldn't start, PC couldn't see it at all, etc. Managed to get it started using an sd with patched navcore/map and now it's running nicely, BUT there is absolutely nothing from the internal drive at all.
I just wondered if anyone else has had this problem and if there is a solution. I think the device drive was formatted probably, or maybe dropped, just a guess.
Any help appreciated
Sorry just realised I posted in wrong section.

Thanks. Yes, that's the plan. The PC installed the drivers for the bare unit as soon as I connected it but no recognition of the drive after that. Neither TT home or windows explorer can see it. Only the sd card once inserted. This makes it very slow to boot up from scratch but otherwise fine.
I just wondered if I could trick the pc into recognising it somehow. I guess it might just be damaged?
Do "deep reset" - reset device with paper-clip, then push "ON" button and hold for about 20 sec - you'll see black screen with white text (like this - Identification Of models )
Take a shot from it and post here - your internal memory maybe problem will be clarified
You have a good unit - the X20 range is a very good model range. You have an intact ROM, otherwise your SD card would not have worked. Having played around with this series quite a lot, in the past, it sounds very much as though your internal 2GB memory is screwed, which is a pity. I cannot tell you what the internal memory location would be on your PC as it varies a lot depending on the removable/fixed drives you already have. However, you are fortunate in that you can obtain very fast SDHC memory cards of 4GB and more that should not slow performance down too much, e.g. a Class 12 card is not going to be much different in performance terms compared with the internal memory, but certainly avoid using less than a Class 6 or you will think it is slow. Also bear in mind that although the 520 was regional model, rather than a Europe version and a larger map takes longer to load than a small map and if you have several maps, remember than it checks all the maps before booting to the last one in your TTGO.bif file.
Any plug and play operating system should see a removable hard hard which essentially is what the unit it. If it does not, it is either corrupt, ruined beyond repair, or at least one file in the map directory is corrupt which stops booting stand alone. Connected to a PC without a memory card in it and not being seen suggests one of the first two. TTHome will not see the unit if TTGO.bif is missing from the unit, even though a plug and play OS would.
Sorry that this is not really much help, but best advice would be use a fast SDHC, install 9.026 onto the card when TTHome prompts you. Advantage is then in the vehicle when you stop, it shuts down automatically and starts when you turn the key, assuming your cigar socket is only live with ignition like Vauxhalls. Ford requires a manual shutdown and restart. Sorry I am a biased ex test driver for Vauxhall
This is how the X10 units worked, but TT have only just fixed this in navcore 9.026 for the newer GOs.
WOW! Thanks for those ideas. I have a GO930 myself so i have a fairly good idea how it works but you have certainly given me some more things to try out.
I'm also intrigued to know what rusigor might be able to tell me from the raw device data above and if that might help. If I accessed a pc running linux for example would that be able to see the device drive? Or would there be a hardware fix out there?
Anyway I will give those things a go and see what happens. Brilliant! Thanks again guys.

..after row "SD Card capasity:"
you should see 2 rows more:
- Internal Flash capacity: (2007040 kBytes - 720, about 1003520 - 520 I guess)
- MMC NAND version (PRV): (bla-bla-bla Samsung - my 720)
- your internal memory is dead.
- but you are lucky guy! You still can use enormous amount of SDHC card - up to 32GB...
PS I had a case when similar 520 device didn't start at all - NANDflash and Residential flash went off, device almost died... Only replacement of these parts converted unit to 720 and recovered from total death...
PPS So - cheer up! You have no more internal memory - now you have ONLY 320 device (which has only SD-card, no any internal memory) - but what did you lost? Buy another SD-card - and be happy!
PPPS Check up your DeviceID - which gave you this engineering menu with one on a sticker - are they match? It can occur (when part of hardware goes off or replaced) that DeviceID changes (just curious about this - in my case, when broken parts were replaced by analogical from 720 unit - ID showed rather new unseen numbers)
