cliny, big thanks for Nuvi motherboard photo. I see this every week, but for another users this picture is interesting. But this picture is right not for all 1xxx, may be for 7-8 PCB version. Not only SanDisk memory bank can be used, I see Samsung memory at this time at broken Nuvi 1310 on my table:-). Different PMICs, different LCD controllers. Nuvi 1xxx produced in 2009 is not Nuvi 1xxx produced in 2011. And if you have 1 Nuvi - not say about all, please!
