How do I install TomTom HOME?
TomTom support page

I have managed to solve the problem of loading a new map on my Go700 using a Mac. I discovered that Tomtom is incompatible with the Leopad operaying system, despite the protestations of the idiots at Tomtom ,so I reverted to an older Mac using Tiger.
Taking the instructions given to crinold, I tried to erase the disc on the 700 using home 1.5 - and it didn't work. So I went to disc utilities, highlighted and erased the Tomtom disc, and opened home 2,5. After being refused entry several times, like being told to load an already loaded device, I persevered, and managed, slowly, to add the map I had bought for 78 euros. T]One point oif interes is that when I bought the map, they site stated it would cost 63 pounds sterling, but switched it to euros when the invoice arrived. at a rate very favourable to Tomtom - funny, that.
This is sharp practice,probably illegal in many countries,, but, to be honest, dealing with the mysterious Tomtom company is so frustrating, that I don't have the time or inclination to fight them for the money they cheated from me.
How they survive with such an awful product and extremely bad after sales service is hard to understand - perhaps they won't ... we live in hope.

I had the same problem how ever after downloading all the software updates and pretty well evey thing that was available on the tomtom home sight suddenly the map was there. It could be a soft ware bug.

my tom tom 510 would start, i have charge the tomtom with green light on, but tomtom is not coming up

The problem is caused by a version mismatch between the Application version and the Map Version. They must both be the same. For example, if the TomTom has not had the application updated, but you updated the maps, the TomTom will not know how to read the file.

Make sure that if you are trying to use a version 815 map, that you are using a version 8.XXX application too. I had to upload two application version changes before I could read the new USA maps.
