I have a Mio P550 with Tom tom 6 installed, when I try to run Tom Tom all I keep getting is no valid GPS

Hi Dave,

First off, go to your GPS settings. Make the GPR Program Port: COM4. In the Hardware tab, make the GPS Hardware Port COM2 and the Baud Rate 4800. In Access, have the Manage GPS Automatically checked.

Download the VisualGPSce freeware program from this site install and run it. Make sure you're outside (sorry), you should see the to bars filling and after a while the red light in the bottom corner will turn green meaning you have a lock.

Hopefully now when you turn TomTom on, you will have your position shown. I always need to start VisualGPSce before kciking TomTom off.

You'll need to find the firmware (ROM) image file (Google) and then: Connect the mio p550 to PC
1.put the Button of the PDA in ON position
2. hold the joystick downward and press the reset button
3.choose "Image Upgrade tools"
4.choose "0=Image by USB"
5.intall the usb driver (PC require the drivers). The driver in the
folder "USB driver" the software "dnw5.0e"
7.(if you want to make a test of connection USB, click the" USB
port/Statute". If all is ok go to step 8
8. click "USB port/transmitted" and to show the way of the file
"MioP550 - Osc260A R05_P09.nb0" the reset button to restart the mio p550.

Good luck!

Have lost manual. I need car charger for Mio P550 but Mio no longer making. Have purchased Scala AC Travel Charger Part No; SEL15305 (Input voltage 100-240VAC, 50/60Hz) and end is right but not sure if it...

The important thing is the ampage. If you have your old car charger check the ampage output. A higher amp rating charger will be ok as the p550 will only draw the current it needs. The voltage you listed sounds like a house charger not a portable car charger. cars run at 12v and the output should be something like 5v dc - 1amp (normally anyway).

Mio c220s canadian version

I would thnik you could download the US maps from a US cd that came with their unit to an SD card.

The C220 for the US comes with 4 states on the GPS and the rest on an SD card that is in the side of the unit
I downloaded the 46 maps form my cd to a 1GB SD card that I put in a sot on my computer.

Mio P550 reboots but does not take any touchscreen inputs

I had the same and contacted MIO (use the phone number for your country,
). It was related to the shock the screen got and they graciously changed it for me (it was during the second year of the warranty). If the warranty has expired, you are probably looking to about a hundred bucks expense.

Mio P550 how do i do a hard reset

on/off switch in "off" position for at least 30 seconds, then turn it in "on " position, power on and "reset". You'll lose all your data and all the installed programs.
Alternative: using the screen options, go to "system info", and choose "hard reset".
Beware: pushing the joystick down while doing a reset will get you a boot menu with memory-formatting options. Choose "exit".
Otherwise look into xdadevelopers forum (Google it or go to, say,
Mio P550 / P350 ROM upload [Archive] - xda-developers
A good idea would be to backup your data in the first place- just a hint.
