Isuzu oem navi system signal problem

**PATSYS50** · December 17th, 2012 08:10 AM

Hi guys,

Any of you who has the originally installed isuzu navi system having problems with getting signal?

I am not sure when it began but during the first year I bought my Alterra, navi signal is good and almost everywhere.

Now when I use it, it mostly has 0 signal strength. There are very occssional times it gets signal, one was when I was in san miguel ave in ortigas center but that was quite inconsistent (I tried passing that route again but now no signal).

My chip is updated with laetst from iNavi.

Is there anything I can do to boost the signal of my Isuzu navi system?

Thanks in advance.

I had that very same problem on my 2011 Alterra a few months ago.

On the top of the dashboard there is a "receiving" unit for signal reception.

The inav technie who met me at my dealer believed it to be faulty and proceeded to replace it. As he removed the bezels from the dashboard to access the head unit, he realized that the lead (jack) from the receptor on top of the dashboard to the head unit had worked loose and was not fully seated.

He replaced it (the receptor and lead) in any event, maybe because I was there chatting with him. At my suggestion, he relocated the top dash unit to the passenger side rather than the middle of the dash. It has worked fine ever since.

During very cloudy or dark skies, the signal is not as strong as very clear sky days for reception as evidenced by the signal strength meter at the bottom right of the map. I think this is probably normal as my previous vehicle had this reception problem in "bad" weather.

Ciao!

had my receiver replaced several times to no avail. blame it on my 3m magic tint that is heavy metal so to speak. i had to buy a re radiating signal booster to make the signal ranging from 9-11. cost me 2500 to get it going again.

Hi fireblade,

Where did you buy this and is the installation DIY?

Thanks
