the most ideal way is to clean the small surface that u goona need to stick the meter holder with THINNER. don fret using thinner on the dashboard coz it wont discolour or damage the surface. allo u gonna need to do is visit the accesories shop that u frequented and using a small cloth, just dab a little and just scrub the area u needed and the meter holders base of any previuos glue residue, then u may use 3m or ciplak double sided tape from rm2 shop. that alone will do. reply here about the outcome.
