Resurrecting an old thread rather than starting a similar new one.
My last two visits my SunPass transponder has had issues - in January about half of my passes through the toll plazas on 417 didn't register. And on my trip last week none of them did. I can think of two possibilities:
1 - after six or seven years, the transponder is just worn out
2 - because I hadn't used it since pre-Covid, I forgot and mounted it in the lower corner of my windshield instead of right under the rear-view mirror. Is this incorrect placement enough to cause a mis-read?
Even though I registered my rental license plate in the SunPass app, the system still didn't pick it up as an existing account and instead I get the Dollar fee (full-rate toll charge plus $20).
I'm thinking I should just go with VTP in the future but if simply mounting the transponder in the right place will fix the problem, that's more convenient.
Thanx for any experience here.
