Hi all its me again (sorry)
With much help from you all I have managed to put on navcore and truck maps on my Go700 (as per sig)
I have now just got a refurbished Go 530 with SD card slot and 4GB card.
I have never had a tomtom with a SD slot so here goes.
On the hard drive I have UK and RI map 830.2305 with navcore 8.351 boot 5.5120
I want to upgrade this map.
The main reason I bought it is to put Truck map and navcore onto SD card (as per my sig)
What difference is there putting maps on SD card as opposed to HD drive I have read about boot drives what is this please and how do I go about doing the above.
Thank you.
