how to upgrade the NAV600 to a NAV900.

[desmo]

Hi all I have done the 600 to 900 upgrade without problems & got a  2018/19 card but since the upgrade the tmc is greyed out (traffic announcements) in settings. any help to sort this would be much appreciated thanks

Hi desmo,
sorry i cant help, ill check mine tomorrow and see if its the same, which links did you use to upgrade? the first page ones?
just asking as i used the first links and have a new map card, I'm just worried about putting the new card in after using first links in this post, which i think are V181

cheers
Gary

Hi Gary, i used the first page links & upgraded with no problems at all using 2017/18 map card which i purchased from ebay as only just purchased the car with no map card, after putting in the card it kept rebooting the infotainment system, when i took the card out everything else worked fine so thought i would do the upgrade hoping it would cure the problem it didn't so got a refund on my first card & got a 2018/19 card from Sat Nav Direct all works perfect now but noticed that the TMC is greyed out in settings but if i go into config the nav settings its functional ie not greyed  cheers dave
