Try that and then do a master reset. It might not hurt to use the rwdata cleaner while you do the downgrade to 3.3.
Unfortunately didnāt help. Downgraded to 3.3 + did a master reset and drove around 200 miles this weekend. Still no GPS lock.
This is likely a hardware issue if you do not have the proper voltage to the antenna. You need to verify this.
I did check the voltage with a multimeter as I stated in one of the last comments. I have not checked it again once downgrading to 3.3. I can check it again if you think it has possibly changed. Iāll just have to pull my dash back apart.
No voltage to the GPS antenna. What should I do next?
Find the reason.
If I knew how to āfind the reasonā I wouldnāt be asking for help.
