Mio 168 Strange problems

Hi everyone! I hope someone out there can help me. This is not the usual connector problem (which I have suffered from in the past).
There are 2 issues:
I have had my Mio 168 + TomTom 5 for a couple of years now. It has always been very slow in registering satellites, but now it is beyond a joke. It can take more than 15 minutes, and even after that it will drop out for 5 minutes at a time at irregular intervals.
If I set the display to “show GPS status”, it shows a quite healthy situation with seven or eight long bars, but it does not register my position and turn the bars blue until those many minutes have passed. Using the extension cable increases the bar length, but does not make any difference to the time taken to register. I can, in fact, monitor the “dropping out” when, after the Mio registers my position, the blue bars immediately fall to almost zero – then rise again.

I thought that in order to cure this, I perhaps needed to reinstall TT5 on the PDA, but when I try to do that, another problem arises. The PC tells me “USB device not recognised” and refuses to connect. I wanted to do a hard reset, but am afraid: a) I don’t know if it will make my GPS receiver any better, and b) I don’t know if I will be able to connect afterwards anyway because of the non-recognition issue.

Sorry to be so long-winded, but I have tried to describe the symptoms as accurately as possible. Can anyone help? Please. I love my Mio but it is driving me crazy at the mo.

Thanks, but I have tried that before and it doesn't work. The unit has always worked fine on "TomTom Cable GPS". However, because you kindly took the time to reply, I tried NMEA again. Nada.

I have tried tomtom cable setting on my mio168 in the past and found the signal not reliable and found the NMEA setting to be reliable all of the time

Well. Who would have thunk it! The NMEA setting really does work! I have used the TomTom Cable from the first, and never would have thought to use another setting. Anyway, NMEA does seem to be more stable and faster reacting. Thank you very much indeed.
Now all I have to sort out is the PC/USB connection. But that it less urgent now that my GPS functions again. The connector did go wrong about 12 months ago and was changed. Perhaps it has gone wonky again. Pity, I won't be able to update speed cameras.
Thank you once more for your splendid advice.

Use a card reader to install/ update the speed cameras on the device - Mike

Cant help you with pc/usb connection, I have used my Mio168 for over 2 years and never had a problem with connection, i use it for interfacing with Outlook for keeping Address book uptodate, I presume you have Activsync Installed which works very well.

As you have TomTom 5 on the SD card will be a number of folders one of these folders is the Map folder it will be quite obvious from the folder name "Great_Britain" or "Western_Europe" etc. Into this folder you copy/ Paste the POI files, each POI category comprises of a bmp file (the icon image) and an ov2 file which contains the individual locations within that category.
