This region contains vital information and can be restored to fix future problems in many units. The vast majority of units which will turn on can be fixed one way or another quite easily as follows:īefore you do anything, make a copy of your unit's region 41 via SD card, details below. In any case, such a unit would not be economically repairable and would be better broken down for parts such as screen and case and the entire board junked after any salvageable parts are stripped. There is a fix for that, but it involves replacing/reprogramming the chip and is not to be done without highly-specialised kit. There are a very tiny amount of units which exhibit that symptom but it's due to a physically damaged flash chip. So, if you have a modern 'nuvi-type' unit which is stuck on splash, the chances are 99% that it can be un-bricked.
For further details on possible fix of a totally black screen, see Post #5 and for one with dim light.
Even if your unit appears dead, it may still be be possible to revive it if there's a very faint light showing on the screen in a dark room or even if the screen's completely dark. This is related to the mode that the older units rely upon solely to flash firmware and update maps etc. Most units stuck on splash cannot be seen in Mass Storage Mode but can still attain pre-boot mode. I'm using the term 'brick' loosely as it applies to a unit which will switch on but not boot past the logo screen or 'splash screen' to use the more specific term. Fortunately they are also very easy to 'un-brick'. One disadvantage in the 'file system' units such as nuvi series is that they are easier to 'brick' than the older types.
In 'nuvi-type' units, the visible file system is formatted in FAT16 or FAT32 and is contained in region 48 or 83 depending on series age. Both types of units have the internal memory divided into 'regions' which contain pre-determined and very specific information for the unit or generic for the model series. Older units such as StreetPilotc3x0, 26x0 or earlier and many GPSMAP models do not have such a system visible to a computer in Mass Storage Mode. Modern Garmin units have a visible file system.
