BlackVue DR770X Dashcam slow to lock GPS
Last week I fitted a new BlackVue DR770X 2CH-II to my 2023 150 GXL. An expensive item but it is my 4th dashcam over 4 different vehicles and I have found that the cheapies do not last long before something goes wrong. This BV model has front and rear cameras, 3-dimension accelerometer and GPS for speed recording and journey mapping, supposedly among the best.
While the video recordings to date are excellent, the GPS is, at best, an under performer. It typically takes over 15 minutes to reliably 'lock' onto satellite signals and provide a record of speed and location. That can be as much as 25 kilometres travelled! I have logged a case with BlackVue but they have just listed a number of possible reasons why it won't lock quicker. Eg Corrupted SD card, being in an underground car park(!!) or faulty firmware. For comparison, the Prado's navigator locks onto sufficient satellites even when parked in my metal-roofed carport within 30 seconds. Similarly, Google maps works fine on my Android phone.
One suggestion was that my vehicle could have metallic heat shielding manufactured into the windscreen glass, which would attenuate satellite signals. I have searched the Prado's Owner's Manual and can't find anything related to the type of glass, or affecting secondary GPS, mobile phone or toll-road transponder signals.
That brings me to the question: Has anyone else had experience with mounting GPS receivers, dashcams or toll road transponders in their Prado?
