I emailed Meta, got a name of a local dealer who said:
Thank You for choosing REVSwest.com For your enquiry
I'm sorry to inform you that the Meta N99 unit is no longer available
The replacement alarm is the N99T2 which is available at £299 inc. VAT
The price includes supply, fitting and also includes the removal of the old system.
Subject to survey and removal of the old unit not being too labour intensive.
if you wish to proceed with this, please call our Torquay branch on 01803 297949
and we can book you an appointment.
Many Thanks again
Any tea in the pot?
