|
|
Probably a stupid question, but I don't want to break the unit
After experimenting for the best position on my e46 bmw 3 series, I have installed the magnetic sticky baseplate on top of the rear view mirror. The signal strength here is excellent (I have the climate comfort screen which destroys the signal - there is a gap in the screen around the rear view mirror).
The cradle won't fit here though. I'd like to hardwire the power supply - am I safe cutting the cigarette adaptor lead and hard wiring that? I was surprised that the official hardwire lead is a different connector which only supplies the cradle.
Any advice appreciated. I attach some pics of the install (which I can recommend for any other 3 series drivers)

I don't think you can do that. The TT BT GPS accepts 5v and the conversion from 12v is carried out inside the cigarette lighter plug. If you hard wire the lead you'll be passing 12v to the GPS and will fry it.
If you use the cradle and the hard wire lead then the conversion takes place inside the cradle. To do what you want to do without the cradle the only way would be to connect a cigarette lighter extension lead to the existing cable and then hard wire that into your vehicle. _________________ Darren Griffin |

Thanks for the prompt reply Darren! I'm glad I checked before carrying on. I'll let you know how I get on. |

You might want to think about getting a re-radiating antenna (cost about 50ukp) which you easily can fix (by magnet) to the roof of your car and keep the TomTom unit anywhere you like inside the car.
I did this after weeks of struggling to get satisfactory sattelite fix and I have to say it works brilliantly now. Almost 100% of the time I have a fix within seconds of switching the unit on.

I've now fitted the cradle to the same location, and the reception is spot on. Cables are neatly tidied away as well, hardwired to the fusebox. I'll try and post a pic of the new setup in daylight when I can.
However I can recommend this location to any bmw drivers with the climate comfort windscreen.
I've even got the origin b2 gps aerial sitting at the other side of the rear view mirror - and it's finding a signal very quickly as well. Very happy I am! :D |
