    Dont! The same happend to mine, your F20 has a 2 year warranty and as long as you can prove you purchased it within the last 2 years you can get it repaired for free.

    They will even send you a parcel to send it out in.

    However dont make the mistake I did, I could hear it rattling inside so like you I took the screws out to see what the problem was and the usb/power port fell out (well it was obviously not attached!).

    Now they are trying to charge me £60 which is almost half the price of the unit brand new to repair it because "it was caused by user actions"

    Which is total and utter rubbish. I suggest you contact Navman immediately and let them know that lots of people have had this problem.

    Personally I think its poor design to put a power port directly on the board where it has to support constant unplugging and plugging in (lets face it you dont leave it in the car over night do you!) and soon gives in to wear and tear.

    If I dont get a satisfactory answer to my letter of complaint I will be reporting them to Wathdog and hopefully more users will come out with the same problem and the poor internal design will come to light to the general public and how poorly they treat their customers.

    Likewise you can bypass the problem by bying a traffic module as it has its own power source, I picked one up from ebay for £20 if I remember.

    I however need my f20 updated in order for the module to work and in order to upgrade I need that bloddy usb port :/ Hence my stand off with navman.

    Im glad someone else has posted saying they could not directly open the unit as this proves end user can not access the internal workings easily and they are just trying to con me out of more money.

    And why Iw ould deliberatly break my power port I dont know!

    Scam merchants to be honest. Come on navman do the honest thing.

    Same thing happened to my Navman f20. I opened it myself & could see that the power lead connection had broken away off the circuit

    board. I agree -very bad design have all that load placed on a fragile


    Dont try & fix it yourself as it looks near impossible to solder it.

    Try to get Navman to fix it.

    USB port broken loose and fell INTO the device....

    I work with some VERY VERY talented Maintenace men and they were able to open the case and solder the USB port back into place... HOWEVER ... there are "leads" that need to be soldered as well... this was something they could not do... all of them told me the same thing... a "human" did not solder this.. it had to be done by a machine..

    Navman want's $149.00 for repair ... I can buy a brand new GPS for $160.00 - I will NOT make the same mistake this time.... the workmanship on the Navman was substandard at best ...

I have recently acquired a Navman F20 Satnav with a broken USB port (It was rattling around inside the unit.)

I took apart the case and re-fitted the USB port with no problems at all. Just with a steady hand and a fine tipped soldering iron. I also superglued the port in place to add extra strength.

Put it all back together, and it now charges and connects to the PC exactly as it should.

So, before you throw away a sat nav with this problem, contact me and I can fix it for you, or, alternatively I will offer to buy the broken unit from you.

    i had same problem with my Navman but the newer S series... pulled it all apart and found like everybody else that all the power contacts broken clean off even taking away chucks of pcb with it and realise that it was impossible to solder back on... so having nothin to lose and everythin to gain i decided to bypass the battery by cutting cables that goes from the battery to the circuit board and chopped my power supply cable of the cig lighter charger and soldered on directly. so now theres no battery and is getting power directly and so far it seems to work fine.

    it seems to even retain memory as well despite the fact i thought it would need the battery for memory retention.

Garmin nuvi 1300 will not power up

Common problem is a loose/broken charger port. This will prevent the unit from powering up when connected to an external charger and will prevent the battery from charging. The unit will appear dead. The USB port must be replaced or repaired. More info on this problem can be seen here: SHARCNET USA Out of Warranty GPS Digital Camera Repair

Remove memory and put it back, if it still does not work memory is probably faulty.

Garmin nuvi takes days to charge on house current, will not charge in car... new battery, new cables, no help.

Have you inspected the USB port? Common failure on these units are loose/broken USB ports. A broken port will prevent the battery from charging.

Garmin nuvi 2555lm battery want charge

A common problem with these units are loose/broken connections on the rear USB port. There are 5 pins on this port. If the power pins are loose/broken, the unit will not be able to charge the battery. The unit will not turn on because the battery is dead. Even if you plug in the charger, there battery will not charge.

The unit will not charge the battery if it won't turn on.

While you could have a bad battery, the Nuvi 25xx series is not that old and the date code on the battery is probably from 2010 or later.

If you plug in the charger, the green battery status indicator should go away or you should see a lightning bolt appear over the battery status indicator . If you don't see a change to the battery status indicator when you plug in the charger, then this confirms that the rear USB port is broken and not applying a charge to the battery.

Port for car charger broken

the following advice pertains to the following magellan gps systems.

Magellan 800, 860, 2000, 2200t, 2500, 3000, 3050, 3100, 3140, 4000, 4040, 4050 and 6000t

i fix these and many other magellan gps daily so when considering my advice , please understand i do not google my solutions.

assuming your car charger is working (the little green light is on) and your magellan still wont start up after holding the power button while its plugged in for up to ten seconds and still does not below

this is actually a very common problem with these magellan power ports...they are poor quality from the factory and always and i mean always fail..the new ports that you find on ebay are 100% better then the factory port.

if your able to replace that power port yourself, you can get one HERE, if not, ask the fellow that sells them for help.

due to some dubious "experts" on fixya, im not permitted to help you directly, but please follow the link above to get further help.

let me know if you need more help or info

How to open navman F20 to replace the battery

There are 2 small screws at the bottom of the unit, remove these and place a flat screw driver or knife in the joint that runs around the unit and prise apart, being careful how far apart you pull as there are wires attached to both sides, the rest is easy as the battery just pulls out and the new one goes in the same place.

Touch screen not responsive Garmin 680

The cable to the touch sensitive part of the screen may have come loose (easily happens if knocked).

Try taking the unit apart (with care and the right type of screwdriver) and reseating the connector cable.

Once you've done this you may need to recalibrate the screen. Holding the power switch down will get you to the reboot / recalibrate screen.

But of course this will probably invalidate your warranty so beware.

Loose part at the power input point.

it comes apart take out the 4 screws in the back. you'll need something to pry the back off .start on the side with something thin to unsnap the 2 halfs then use your fingers. after openning you'll need to resolder the powerport back on with a soldering iron and new solder. 4 spots hold the powerport on. it will be stronger than before. mine worked fine after.

I hooked the Garmin 340 up to the computer via USB

I strongly recommend you to get it repaired if it is inder warranty because once you break the seal you will loose your warranty service.
And since it is a sealed unit to take it apart you will need some special itype of nstruments which i don't think are available anywhere.
