Hi @co318is

I am afraid you will have to wait until Monday for @VikramK or @lampard to have a look at this and activate the maps if they can.

Hi @co318is

Welcome to the Community! I've re-activated the Western Europe map on your device, Just connect the device to TomTom HOME and check for updates.

Regards, lampard

sill having problems finding satellites
and getting this message
The current map does not support truck attributes.Car routing applied.
not good when drive a hgv,
if I buy another newer tomtom which one will support the truck map sd card.

Hi @co318is

You cannot use the SD card with the truck map on it in any other TomTom unit. Maps are tied to the serial number for which they were supplied or purchased for.

There are truck specific TomTom units.

Finding sats will only work with cold start. Starting from standby doesn't work anymore since WNRO. For car navigation, there's a fix, but for truck navigation, there isn't. Only workaround (google for "suicide.dat").

There is now an unofficial solution. Basically, you have to update the firmware of the GPS chip. After that, finding satellites works again without problems.

what you need is the unofficial GPS upgrade Sirf3 GWS3.2.5 or GWS3.6.0
So I've flashed several sat navs successfully. It can be found on a German forum.

GPS chip SIRF-III upgrade from version: GSW3.1.1 or GSW3.2.4TT3 to version: GSW3.2.5TT3 or GSW3.6.0
for TT GO 510, GO 520, GO 630, GO 710, GO 720, GO 730, GO 715, GO 920, GO 930, ONE, ONE (v2), ONE 3Rd (v3), GO 7000 Truck, Rider 1 + 2
The "Standby Problem" is now fixed (renewed Sat-Fix after standby within a few seconds).
the device list for which the firmware upgrade is suitable:
