Confirm you have bootloader 5.5015 or higher.

just added BL5.5128 and its still the same issues?

please confirm you have used the clear flash tool 3 times and done a hard reset since the bootloader update

Confirm that the card is not write protected.

pc doesnt see the deivce because it doesn not see the card so i cant run clear flash tools

also i reset via the rest button and still the same, is there another reset i should do ?

card lock button is not locked i have written info to card via a card reader it see card no probs and the tom tom see another normal sd card no problem

Confirm that b/l 5.5128 was actually installed. What brand card are you trying to us?

sandisk card, how can i confirm BL as its doesnt have a bif file yet to open as the device hasnt booted

device say bl 5.307(chksum 8307)

seems it is the bootloader that is the issue, but im confused as to how i update it, copied the 5.5128 system file to the card and the device still would not see the card, so how else can i flash the bootloader?

start it with your old sd-card if you have it ? and you see bootloader version. install new bootloader with this old card if needed
system file need to be only one boot in sd-card then you dont need it at all

EDIT: i see you must update bootloader

i use an sd card with a sytem and map on it with the updated bootloader insert it in any tom tom and it will update the bootloader file to the tom tom.
I then shut down tom tom and insert sdhc and it finds it every time

thanks all sorted booted it with a card with 55128 on then switched off and put new card in and all works

you guys are great
