Hi to everyone, sorry for my english...

i just want to report something "strange" about google map app".

does anybody have the same problem like me...

if i launch google map only with iphone, the blue gps position is correct on the map.

if i just connect it to the appradio, the gps blue position move 20 meters away ( appradio even turned off !!! ? )

so when appradio is on, with map application, i'm 20 meters wrong...

maybe stupid question but is that due to the bad installation of my gps appradio antena ?

i mean i've stick it in "reverse" position, not on the sky direction.

in my old avic F700 it was in vertical position and work fine !!!

if anyone can help , thanks a lot, i will try this week end to change my gps antena position in the car

finally it was just due to the bad position of the gps antenna...just move it, one quarter left or right...that change all...

oh.. i had this issue too. Didn't know it could be the GPS antenna. I thought it was the way my iphone was position.

Thanks.

when you're the one to have this problem and no one can answer...

happy that it can help !!!!
