After a long of haggling of support to respond to my question I was cleared to purchase a microSDHC card for my VIA 220. I did so with a Patriot LX 16GB class 10 microSDHC card. I put it in, watched it tell me that it is reading the memory card then fired up MyTomTom to load up the US & Canada map. That's where the fun stopped - when I get to the Insert a Memory Card I click continue, watch it sit on the "Checking for a Memory Card" screen and then jump back to "Insert a Memory card". No error message, no indication of what went wrong.\r\n\r\nI'm really starting to regret my TomTom purchase - support has been painful and slow and the software is very fragile. Any thoughts on what to do next?
