I have not. Mine still works lovely and it's my 2nd one (referbed)
The 1st one i got lasted me almost 6 year. Untill one day i broke the screen whilst it was trapped in my dashboard. Due to how comfortable i got with the tomtom (the version i had) I sought for a referbed one. I found one, £50 on amazon, came like brand new. I love it, it's fantastic although it's also very basic. It does the job. It's not a swiss army knife of satnavs but it's the reliable butter knife of satnavs that's been in yer drawers since ye was abeet 2.
