What devices does the App work on?

Apple iPhones and iPads and Android Tablets and Android Smartphones. Due to the nature of the Android market, we cannot guarantee that every type of Android device is compatible with the App. However, we’re committed to ensuring the most popular devices are catered for on an ongoing basis.

How many devices can I use the App on?

Each username and password will only work on one smartphone and one tablet. In order to arrange access for more users or devices, please call Glass’s on +44 (0)203 897 2500.

How much storage does the App typically use on my device?

Downloading both the App and the associated months’ valuation data, will use roughly 250 MB of storage capacity. This is the equivalent of about 2 mp3 albums (music files).

The App and the data has been specially compressed to ensure minimal storage space is required.

The App states “setting up – please wait". Why is this?

Each month, the first time you value a vehicle by a particular manufacturer, that data is unzipped and decompressed. This is done to ensure the size of the data downloaded to your device is small, quick to download and takes up less memory. The "setting up" message will only be displayed once per month per manufacturer valued. Low volume manufactures will be set up a lot quicker than larger manufactures.

I cannot find and value a vehicle using the Registration Number search. Why is this?

Your device must be connected to the Internet to use this function.

Not all vehicles are valued by Glass’s, particularly rare, new or exotic models. Try searching for the vehicle manually using the “Used Car” search.

How do I adjust the valuation for high or low mileage?

All valuations provided by default are based on standard mileage for that year and plate. To adjust mileage use the mileage slider. The mileage slider spans left to right in 10,000 mile increments. Far left you'll find average/standard mileage.

If the vehicle has been valued using the Registration Number and the device is online, you can enter the exact mileage into the mileage input box. Please note for exact mileage adjustment, the device must be connected to the internet. Mileage adjust in this instance is to the nearest 1,000 miles.

What valuation data is available on the GlassGuide App?

The GlassGuide App contains circa 65,000 vehicles (the traditional printed guide contains a maximum of 13,000). All have Glass Trade, Grade Hi/Av/Lo and Retail Asking values. Depending on mileage, all can be mileage adjusted (excluding premium and exotic vehicles). The standard average mileage values are the same across all Glass’s Products. Mileage adjustment is rounded to the nearest 10,000 when using the manual “used car” search and 1,000 using the registration number search.

What happens if I log into another Glass’s product or service with the same username?

The GlassGuide app will still keep you logged and shall function. GlassNet can only be logged into one machine at a time. The number of devices your account will work on for the Glass's Guide App is dependent on the volume of subscriptions paid for.

Can I save or favourite data?

Every vehicle search completed on the device will be logged in the History tab. This is a basic reverse chronological displaywhich allows valuations to be rerun or deleted.

How do I switch between Retail Asking and Retail Transacted values?

Each valuation page will show a blue toggle button to switch between "Show Retail Transacted" and "Show Retail Asking".  Note how the column label changes.  Users can also set a default retail value by switching on or off Retail Transacted via the Settings cog.

How do I value a vehicle for a previous month?

Historical valuations are accessible by firstly valuing the vehicle for the current month.  To access the prior month's valuation, tap the drop down box and scroll to a prior month (up to 24 months ago).  It's important to note that your device will require internet access to access historical valuations for data months that are not stored on your device.

How regularly does the valuation date update?

The valuation data is downloaded once per month. When new data is available a little red ‘update’ icon will appear above the Settings (cog) icon. Please note that the app will hold up to three consecutive months data offline. This process is automatic after the update selection is made.  Your device must be connected to the internet to download new valuation data for that month.

How do I know what valuation month data I am using?

Each valuation page states the valuation month within the drop down box.

I have access to GlassNet and GlassGuide App – can I see a combined history?

No. The two systems are completely independent apart from the username and password used at login.  Vehicles valued in the App will not appear in GlassNet and vice versa.

Is the usage of the App limited in any way?

No. There are no capped usage limits with Glass's Guide App unless you have been specifically advised at the point of sale.
