i have a nuvi 300 and have just paid a lot of money for the v9 nt disc full unlock if i load the gb map onto nuvi then go to map settings deselect the v8 i get no traffic i have tryed even deliting the v8 map out of nuvi and sending the v9 map direct to nuvi via mapsource still no traffic if i select v8 map then traffic messages start apearing is there something in the nuvi map/v8 which holds the tmc data :o :o

Yes, the TMC data is included in the base map of whatever map you have. By only adding v9 as an additional map, you do not transfer the v9 TMC information.

However, what you have done is not the correct way to upgrade your Nuvi - when you first run the DVD, there should be 3 menu items - one is "Upgrade your Streetpilot / Nuvi" - you need to select this and let it run through all the steps. This will update the base v8 maps of your Nuvi to v9, therefore fixing the TMC problem.

As always, I recommend you have a full backup of your Nuvi before performing this.

Don't reinstall, or uninstall anything - just insert the DVD again, and hopefully the first screen has 3 menu options.

That'll be the problem then - the update DVD has extra menu items to perform the upgrade... They don't use MapSource, so there's no way to manually recreate the steps (well, technically it uses MapSource to unlock the maps first, and technically it may be possible to recreate the steps, but it's not the correct method to use).

Surely all you need to do (given you have paid for the unlock code) is to go to www.garmin.com, and select to upgrade your registered Nuvi, and Garmin will send you an upgrade DVD for free...
