Time is incorrect on tomtom 330s

You can plug it in your car's cigarette lighter socket, or the USB port of a computer,

hi, best way is to go to tomtom.com there is a lot of information for all models. you can select a link to you tube or load a manual pdf. goodluck.

suspect that your maps file is corruped or lost. this may have occured due to a drop or other inteference such as high magnetic field or eletromagnetic interference.
if you connect your tomtom to your pc you can view inside to see if the maps are in the device. if they are not then you may have to redownload them from any map software you had or from the TOMTOM website using tomtom home.

No, what you see is what you get, there is no slot for an SD card or any other form factor, the internal memory is also not upgradable.

you can get a copy of your XL 330 manual HERE, or by clicking on the Garmin Logo

To reset a TomTom 125, 130, 130-S, 330, and the 330-S press and hold the on/off switch for 20 seconds

YouTube is your best bet- use search strrings like 330s, tomtom 330- you can also look at the 130 and 130s, the models are nearly identical with the exception of size and the "s" designation refers to the text to speech option, otherwise the units are all the same. I've seen several reviews on YouTube about the devices and those will be pretty helpful to you
