That is a great place to start... I just did a full reinstall of both yesterday and I swear in made mine run better.
DONT FORGET to follow the directions perfectly and SAVE your IGO folder before deleting the flash drive!
Let us know if this fixes your issues.
ALSO, how close is your GPS antenna to your radar detector?
well i gotta look up the directions first, and then i will follow them like a german follows commands. lol.
regarding the gps, i have it in the dash, under my steering wheel, along the left dashboard end, and place into the left bottom corner of the windshield(inside the car on the dash).
what i think it might be is....when i had the avic, i had a whole bunch of aluminum insulation tape covering the heat box (since i got a e46 bmw, i had to custom cut the heat box to make room), but i also had black guerilla duc tape covering it.
this time, i redid the heat box, but didn't put duc tape over it, and left it at the aluminum insulation tape. maybe that along w/ some magnetism in the unit could trigger the radar, i will try to cover it up w/ non metal tape.
that should work, right???
