Is there such a thing as an external antenna for a TTXL? thinking of putting mine into a 'pod' in the car. This would need an external aerial of some sort as the pod would be part of the dashboard and affect signal strength. |

No there isn't. There used to be GPS Re-Radiating antennas but these are now illegal.
However, given mine works quite happily in the glovebox, you may well find you have no need of any solution? _________________ Darren Griffin |

When you say 'external' do you mean outside the vehicle, or an an additional antenna to plug into the XL. TT still do a 'plug in', which they claim is waterproof, and so usable outside, but you' need to keep a window cracked.
I've just checked TT says only for x00 and x30 series, but I'd thought more devices than that could use them: http://www.tomtom.com/en_gb/products/accessories/antennas-receivers/external-antenna-for-go/ _________________ Mike R [aka Wyvern46]

The XL does not support external antennas. _________________ Darren Griffin |

I wanted to mount the unit in a pod in the dash. The problem I have come across is the car manual says not to use phones or satnav in the car unless connected by external (attached to the outer bodywork and by cable to the unit) as their signals may interfere with the onboard vehicle computer systems.
Might just be the car maker being overly sensitive! |

Not sure why I continue to be surprised that helpful things keep being discontinued. What is the solution for an athermic windscreen these days? _________________ Mike R [aka Wyvern46]

Modern GPS receivers are no longer affected by athermic screens. SiRFStarIII and later all work fine. _________________ Darren Griffin |

Even those with data connections such as LIVE equipped models are highly unlikely to affect the ECU's in a modern vehicle. They are designed to be hardened to interference, particularly from things as common as a mobile phone.
So long as the nav can receive the signal in your desired location then there is no issue. _________________ Darren Griffin |

Surely that can only apply to active re-radiating antenna (i.e. those requiring a power supply)? a passive re-radiator is no more a transmitter than a satellite dish is. _________________ Tomtom Go 1005

Well yes but I've never seen a passive GPS re-radiator?
The OfCom ruling applies to GPS 'repeaters' which it defines as:
Quote: | active devices designed to re-transmit Global Positioning (GPS) or other Radionavigation Satellite system (RNSS) signals |
See OfCom Link. _________________ Darren Griffin |

Surely if you know your latitude and longitude you are not lost _________________ TomTom Go 540 - V9.058, Map GB & Ireland 860.3101

With my last van, I had a four way ciggy adaptor socket wired in by a vehicle electrician. It was mounted centrally on my dashboard and wired into somewhere behind the steering wheel. When I plugged in one of my devices (HTC Advantage) on a windscreen mount, occasionally either the van wouldn't start, or it started but the power steering stopped working, and/or it started but wouldn't stop - unplugging the device avoided these effects. The Tom Tom devices plugged into the same adaptor at the same time had no such effect. _________________ Dennis
