tomtom one help please

My brother has an old tomtom one.. what is the latest map and core he can put on his unit please? Can the navcore be updated on this device?
Unit info:
Tomtom One canada 310
Western and central europe 2GB v840.2562
app 9.026.483454.2 o/s 473972

Thanks in advance guys

Current mapversion is 950 - May 2015, with 955 - August 2015 coming up the coming weeks.

Latest modified navcore-version is v9.510. Look for Downunder's Universal Navcore Installer.

Thank you i will give all a try

1. There hasn't been a Western and Central Europe map for quite a while. What is your 2nd choice?
2. You really don't need the Universal version. Go with the 9.510 version: Navcore 9.510

Wouldn't that have the same effect?

I have downloaded and installed navcore 9.510 from the link provided.. i then downloaded and install United Kingdom and ROI 950.6546.. however it says i can't use this version of map with my unit??
Any advice please?

That's easy. No meta available.

thought as much.. i am downloading version 6544 right now.. thanks

Quite possible but you won't profit from the extra features the 9.510 navcore gives you in combination with a better map.
I would advise 6492 which has ALG. And of course this has a meta code available.

great thanks

FFR, with the 9.510 navcore, you can use ANY version map, that has a meta code & that you have storage room to load it onto.
