Because the theme of the nuvi 1XXX series and NTU found its proposal, I would like to say a few words, too.
With this card (CNEU 2013.40 NTU) and firmware 5.10 my nuvi 1410 really builds routes not always optimal. I tested using simulation. Address search works perfectly, JCV and LA too.
I think the reason of errors that this card is not suitable for 1XXX, and not the firmware 5.10. This firmware is one of the stable - I tested the Navigator with all firmwares from 5.10 to 6.10.
I hope that I have understood correctly.
