My brandnew ( 7 days old) GPS TomTom 5200 Go , is not helping me with traffic information because the sim card function or GPRS function is not activated or shows " disconnected". I read now ,after having those problems, that many customers have the same problem, but nobody finds a solution. The factory resets ( min. 5 I did) are not changing anything. i use the correct cables and I follow the instructions perfectly, but my GPS remains useless in traffic jam situations or in updating the tomtom services. Who can help me ?
