light. Unit replaced and moved forward
From factory exhaust location.
- Display Home Button not working.
Display replaced.
Miscellaneous likes / dislikes / suggestions
- Apple Air Play intermittent connection /
play issues
- Passenger side front floor mat does not
have hold done pins like driver floor mat
- Tailgate step hits receiver hitch denting
chipping paint. Poor design. Simple
design fix would be to lower height of
receiver 1” lower to clear step. My fix is
to cut thick wall pipe wrap to lay over
receiver / hitch when lowering step with
hitch installed.
- Speaker grill screens are too fragile.
They dent easily. A thick flexible plastic
grill would have been a much better
material for a truck.
- Steering Column extension could be
longer. I’m 6’3 with long legs and
slide seat to almost max distance
making steering wheel father away then
I’d like.
