The E-PASS Uni Comes Off Before the Urethane Work
The E-PASS Uni is handled differently because it mounts with suction cups. CFX places it behind or below the rearview mirror. Remove the Uni before the windshield work, keep it in a protected place and do not leave it loose on the dashboard while driving.
CFX also says that moving a Uni to another vehicle requires updating the vehicle in the E-PASS account. Replacing the windshield on the same car is not a vehicle change.
Before Mobile Auto Glass work begins, take the E-PASS Uni off the windshield and store it beyond the mirror-area work zone. We release the laminated pane from its urethane bond, prepare the bonding surface, apply the new urethane bead and set the replacement glass. Leave the Uni stored until the glass, rearview mirror and trim are installed.
The vehicle must remain parked until the stated safe drive-away time. That time is based on the adhesive system and installation conditions, not on the toll device. Remount the Uni only after the windshield work around the mirror is finished and you have confirmed the correct open area.
Divide the Mirror Area Between the Toll Tag and ADAS Camera
The space behind the rearview mirror may contain a forward-facing ADAS camera, rain sensor, mirror bracket and plastic covers. The toll device needs its own unobstructed position. A correct CFX mounting area does not mean the tag can cover a camera lens, sit over the camera's view through the glass or press against a sensor housing.
Supplying the VIN before replacement helps identify the correct windshield configuration. Windshields for the same model can differ by camera bracket, rain-sensor area, antenna equipment, heating features or an acoustic layer. These details affect the glass selection and the amount of usable space around the mirror.
Do not copy the old tag position automatically. Replacement glass may have a camera cover or sensor outline required for that VIN, and the old sticker may already have crowded that equipment. Start with the completed mirror assembly, locate the clear glass allowed by the toll issuer, then compare that spot with the vehicle instructions. If those directions conflict, contact the issuer and vehicle dealer before attaching an adhesive device.
- Let the mirror, camera covers and rain sensor return to their installed positions first.
- Keep the transponder out of the camera's viewing area through the windshield.
- Place an E-PASS device behind or below the mirror and beneath any windshield tint.
- Use the vehicle and toll-device instructions if either specifies a narrower mounting area.
Replacing the windshield can change the camera's position and optical path. The vehicle manufacturer determines whether recalibration is required. Bang AutoGlass performs ADAS Calibration in the same visit when the vehicle requires it after windshield replacement, where the procedure can be done on site.
Calibration checks the camera-based driver-assistance system; it does not test a toll transponder. After calibration is complete, mount the device in the approved open area and follow the toll agency's process for confirming it is ready.
When an E-PASS Uni Is Not Reading Through New Glass
CFX warns that some vehicles have metal-oxidized windshields that can inhibit a Uni from being read. If an E-PASS Uni does not read after replacement, that alone does not prove that the portable device failed or that the glass was installed incorrectly.
If a metal-oxidized windshield appears to be blocking the Uni's signal, check one variable at a time so you can tell whether the problem is placement, account information or the glass construction.
- Compare the Uni's position with the CFX instructions and move it only to an approved area.
- Confirm that the E-PASS account lists the correct Uni and vehicle.
- Ask the vehicle dealer whether that windshield requires a specific transponder position.
- Contact E-PASS support if the Uni remains unreadable after those checks.
Give us the VIN and describe any prior transponder-reading problem before the appointment. The VIN helps identify the required brackets, sensors and other windshield features while we fit OEM-quality glass. A different windshield will not fix a toll-account problem.
For SunPass on a new windshield, use SunPass troubleshooting directions rather than assuming the CFX warning and placement process apply to a different device.
Florida Treats the Toll Device and Damaged Glass Separately
Florida Statutes section 316.2952 requires a fixed, upright windshield with federal safety glazing and working wipers. It generally bars signs and coverings on the windshield but exempts a device issued by a governmental entity for electronic toll payments. The statute classifies a violation as a noncriminal nonmoving infraction.
The toll-device exception does not replace the agency's mounting directions. A government-issued transponder can be allowed on the glass while still needing to sit behind or below the mirror, below the tint and outside the ADAS camera's view.
Windshield Coverage Does Not Decide the Tag Policy
Florida Statutes section 627.7288 states that the deductible under comprehensive or combined additional motor vehicle coverage issued in Florida does not apply to windshield damage. The section names the windshield, not the toll device. Bang AutoGlass verifies coverage before any work, helps you with the claim and bills the insurer directly. Have the policy details ready if you want us to check how your coverage applies, and use the Florida auto glass insurance guide for more detail. General info, not legal or insurance advice — coverage varies by policy.
Build the Appointment Note Around the Next I-4 Express Trip
Write down the glass and toll-device details together so an unusable sticker or missing portable unit is not discovered after the damaged windshield is gone.
Before the Glass Is Removed
- Photograph the tag and mirror area without pulling on broken glass.
- Record the issuer, device name and whether it uses adhesive or suction cups.
- Provide the year, make, model and VIN for glass identification.
- Mention the ADAS camera and rain sensor near the mirror, plus any dashboard warning lights.
- Remove the E-PASS Uni or another portable device before work begins.
Bang AutoGlass comes to your vehicle anywhere in Altamonte Springs. Leave working room around the front of the parked car and plan for it to remain still through the safe drive-away time. We install OEM-quality glass, form the new urethane bond and recalibrate camera-based driver-assistance systems in the same visit when required, where the procedure can be done on site.
Do not choose a public lot only because a space appears open. Altamonte Springs says public parking is available around Cranes Roost Park throughout Uptown, but event restrictions may apply and parking at the Altamonte Lakeside Office Building is prohibited. If the vehicle is on property you do not control, obtain permission and check posted restrictions before the appointment.
Keep a Storm Warning Out of the First-Trip Test
The National Weather Service Melbourne reports that central Florida has more than 90 thunderstorm days each year. It defines a severe thunderstorm as one producing hail at least one inch in diameter, wind gusts of 58 mph or more, or both. Its guidance tells drivers to avoid driving through a severe thunderstorm by pulling over or delaying travel.
Use an official warning as a travel decision, not a deadline to test the tag. Altamonte Springs works with the Seminole County Emergency Operations Center on flood and storm monitoring and directs residents to AlertSeminole, Seminole Government Television and city updates. City guidance says to remain indoors and off the roads unless necessary and warns that twelve inches of water can carry away a small car. Leave the I-4 Express verification for later if officials advise against travel. Drivers timing damaged glass around a warning can use the Altamonte Springs storm-warning windshield check.
After the New Glass Is Installed
- Obtain a replacement E-PASS Sticker rather than trying to reuse the removed one.
- Remount a Uni behind or below the mirror and below windshield tint.
- Update the E-PASS vehicle information if the Uni moves to another car.
- Follow the SunPass account instructions for any SunPass device involved.
- Check that the wipers operate normally before the first drive.
- Confirm the device is properly mounted and ready before using I-4 Express.
When you request Windshield Replacement in Altamonte Springs, FL, include the toll-tag type, VIN and mirror-area photo through the local booking page. Mention an upcoming I-4 Express trip so the transponder check remains on your post-install list.
The glass installation is protected by the Bang Lifetime Workmanship Warranty, which covers our workmanship and defects in the glass we install for as long as you own the vehicle.
Before Altamonte Springs Drivers Use I-4 Express Again
Can I reuse my E-PASS Sticker after the cracked windshield is removed?
No. CFX says an E-PASS Sticker stops functioning once it is removed, cannot be reattached and cannot be moved between vehicles. Arrange for a replacement through E-PASS rather than trying to save the adhesive tag from the damaged glass. Mount the replacement according to CFX instructions after the new windshield and mirror-area hardware are in place.
What should I do with a SunPass sticker on my cracked windshield before the appointment?
Photograph the device and any safely visible identifying information, then check the instructions for that exact device in your SunPass account. Do not peel an adhesive device merely to test whether it transfers. For SunPass on a new windshield, follow SunPass instructions rather than applying the E-PASS Sticker rule to a different product.
Where should I put an E-PASS transponder on the new windshield?
CFX directs drivers to mount an E-PASS Sticker behind or below the rearview mirror and below any windshield tint. The E-PASS Uni uses suction cups in the same general area. Keep the device away from the forward-facing ADAS camera, rain sensor and their viewing areas, and follow any vehicle-specific placement directions.
How do I confirm a remounted E-PASS Uni before entering I-4 Express?
Compare the Uni’s position with CFX mounting instructions, then confirm the correct device and vehicle appear in the E-PASS account. CFX says some metal-oxidized windshields can inhibit a Uni read. If the Uni still is not read after those checks, ask the vehicle dealer about the required transponder position and contact E-PASS support. Do not use I-4 Express as the first test.
Will mobile windshield replacement near me also replace my toll sticker?
The appointment replaces the damaged windshield and includes ADAS recalibration in the same visit when the vehicle requires it, where the procedure can be done on site. Toll devices are issued and activated by the toll agency, not the glass installer. Keep a portable transponder with you during the work, and arrange an adhesive replacement with its toll agency. Mention the tag while booking so the mirror-area equipment can be documented.
