Hi Milton

I flashed my nuvi 1490t with the modified software and nearly bricked my unit. The main danger is the rollback to V3.00. if you don’t do it correctly, the system gps will not turn on and request you to bring it to a nuvi 2x5 engineer.

Although yours is 1460 so there might be no such problem, personally I find it to be highly unstable(read my earlier post) rendering it almost unusable.

My advice is wait for someone to fix the bugs(traffic receiver software will not stop updating, TSM Duo will not work etc)
