    TomTom now slow to acquire satellite signal

    When I first got my XL335S, it seemed to pick up the satellite signals very quickly, especially after connecting to TTHome. Maybe 5-10 seconds.

    Since then I have updated to a newer map and official navcore (9.026) and it now is much slower to acquire the satellite signal, even after connecting to TTH. Maybe 30 seconds.

    Any thoughts, suggestions?

    When you connect to TT Home are you updating the quick gpsfix files, these will enable your tomtom to get a fix by preinstalling sat positions, these last for 7 days, so a regular update is necessary.

    Did TTH actually download the QuickGPSfix? And is it on your TT (there should be a couple of files in the 'ephem' folder in the root of you TT)?

    Well there are 2 files in the ephem folder (ee_meta.tlv and ee_meta.txt). They are both very small files (1k)
    They are dated 4 months ago (Feb.23).
    Should they have a current date?
    When I connect to TomTomHome, I remember I used to see QuickGPSFix being downloaded. But since I changed my map and received an updated navcore from TomTomHome, I haven't seen QuickGPSFix being downloaded anymore.
    Is there a way to have it regularly downloaded again?

    There should be three files in the ephem folder: ee_meta.tlv, ee_meta.txt and lto.dat. I've included them in the attachment. Extract and copy them to the ephem folder. Then connect to TTH. I think TTH will update them now.

    Thank you. Thank you. Thank you etc.
    It worked like a charm!!!!
    I have no idea how it works, but it works.
    Get signal now in 10 seconds instead of 45.
    Did I say Thank you? :-)
