Pnn 350 new maps

hi mates,

i got one day, 2 years ago, upgrade software for a pronav pnn350. it is a wince based software, so i made it run on cheap 5 inch chinese gps navigator. after two years it broke and i bought me a second hand binatone f435 car satnav. also wince. you can run any software on it. in the moment i run it with igo primo with the newest maps, it working well but actually i like pnn350 it runs much faster on a binatone, cause binatone runs with a much higher baud rate than a pronav device… how do i get new 2013 maps for it please. i know that truckmaps are released around all two years . the latest teleatlas maps for primo is out with 2013.12 , can anyone help me with a new pronav map. i use it especially for London. it actually designed for t h i s city. thanks for any help in advance
