I got one on Temu that works great. Jumped the Mav from a deep sleep and got right back in business. It was around $25. It was the cheapest one I found. It is only around 7" long and can be charged up in the Mav. I keep it right next to the battery just in case.
My overall average is 43.2. Before cold weather set in it was 44.3 with 2000 miles now. Of course high speed hurts, but so does hills and stop lights. I use routes when I can that have less signals causing stop and go. I don't hold people up, I accelerate to the speed limit and then keep it...
The finance guy will tell you anything, and sometimes charge you for things you did not even discuss. Mine did, I wound up getting refunds but it took months to get them.
I have that cover. I noticed the same cover uses different brand names. The instructions left a lot to be desired so I watched an installation on YouTube. I paid around $150 and am very happy with it.
After hearing all the negative remarks about the radio I was expecting a real crappy sound. I got my XLT on 7-31-23. I am more than pleased with the sound and wont be making any improvements. I do wish it had Sirius XM, but I listen to that on Car Play.
I called Ford Customer Service about the price going up $500 and I pretty well got the same response. It would take up to 45 days and they would return the difference to the dealer. My dealer is very interested in good reviews on surveys so I do expect to get the refund.
