When first Formatted my TT and then connected it to TT Home 2.8 the Navcore got upgraded to v7.903 and flashed the GPS FIRMWARE TO v1.21

I now have Just finished upgrading my 4 years old Tomtom GO 910 with Navcore v9.205.547817.1
BootLoaderVersion=55259
Map: Western_And_Central_European v875.3613 with IQ Routes.
But the GPS Firmware= v1.20 (GSW3.2.4TT_3.1.00.12-C35B1.02

I do think that v1.21 is enhanced for better indoor reception or difficult areas (City Centres). Where can I download v1.21 and how do I install it?

Thanks for your help.
