i update with tt home but i have still navcore 7.301
Ok, well as it turns out, your device is now 'out of life' as TomTom realised that 32MB of memory was not enough to support live services so they stopped supporting it, hence no more navcore updates.
You really only have two choices from here:
1. You can experiment with different NC's that can be downloaded from here but you should backup your unit first and be prepared for some trial & error until you find one that is acceptable.
Apparently NC 8.562 or 9.101 should work but it's up to you if you proceed. Another user had some kind of success here.
2. Move on & get another device, there are some bargains to be had on eBay. Personally I'd go for any of these: Go 540/740/940/550/750/950 as they can all accept downloaded maps whereas the VERY latest devices (Sept 2010 onwards) cannot.
thx i upgrade to nc9.101 and install map 930.5601 but when i touch the screen TT Freeze.
is the map not compatible?
You haven't said what country it is but whatever one, it IS compatible but does it have meta data available?
Either way, it wouldn't be the reason for the freeze, it'll be a navcore problem. Try a hard reset by holding in the reset button on the device with a straightened out paper clip or something and try again.
It could be you've installed a bad navcore, where did you get it from? Is it an official one from TT or is it a modded SE one? If it's an SE, then look at the setconfig file.
Like I said before, it's down to trial and error now.
