Where did you see that?

i have a nuvi 40 that has that function and need the 1490 to have it too.

The "T" in the model number (nuvi 1490T shown on the box) only indicates that the device was packaged with a FM traffic receiver in the box. The actual device is still a nuvi 1490.

Will flashing the 1490t firmware give the function and is it even possible? Since i dont know if these two models have same cpu and such

These's absolutely no difference between the firmware used by any 14x0 model. That is: 1400, 1410, 1450 and 1490 all use the same firmware. In fact the 13x0 series also uses the exact same firmware. There are various features which are 'locked out' of some models and can be activated by flashing the senior logo to region 16, however 1490 has all of those and additionally the Routes function which can also be added to the junior models by manipulating the firmware.

ive seen a few conversion threads between different models (ie 37xx to 47xx).

I think you mean 34xx not 47xx. That's because the 3700 and 3400 series share the same hardware and have identical PCB P/N's but run different firmware.
