Hi

I have a nuvi 1300 with B0972 chipset an FW 6.20, it will work this moddification?
Someone with same model who has worked it?

Another thing:
For JCV to works, must I have garmin maps? Beacuse in Argentina the best maps are proyecto mapear, or can I have mapear maps and garmin jcv file?

thanx

Edit:

Well, finally touch my 1300, by the method of SD card, with the normal method the updater.exe doesn't recognize the nuvi

I try with CN South America 2015.30
Line assist: works
Speed limit: works
JCV: doesn´t work (I've tried with 2 different files available)

Any solution?
